ELECOMHUGE Trackball, 2.4GHz Wireless USB, Index Finger Control, Customizable 8-Button, Large Soft Palm Rest, 52mm Ball, Windows PC Mac (M-HT1DRBK)

PROIt is a trackball which is far superior to any other mouse control on the market end of story. The large trackball makes it easy to do fine precision in graphic work. The over 7 buttons and wheel gives you the ability to do most anything any other mouse control device. I almost don't use the keyboard except when I need to create a document or email. I love having all that control in just 1 hand.Another benefit to a trackball is that it does not need much real estate. I have it on the arm of my chair and does not need anymore space cause it does not move around like a mouse. While a trackpad does not move I find it to be much slower, highly inaccurate like using finger paint, and totally horrible when trying to se fine work. Trackpads are an obscenity o technology that only a hammer can fix.Price was reasonable.CONThis is a wireless which means every now and then I have to deal with batteries running low. I also have the USB version which never needs to recharge/replace any batteries which I prefer. I know some people don't mind dealing with batteries and prefer not to have wires all over the place. Wired/Wireless I'd still prefer this over any other device.I do not do gaming.

Quick Summary: MSTE users who don't have an MSTE - get this mouse as it's the closest "replacement" to date. Obviously, if one wants a mouse like the MSTE, then get an MSTE. But even a used MSTE costs a bit and you have to be careful of the cord. If one wants something Less Expensive that closely resembles the MSTE and is also cordless, then this is the best mouse on the scene since the MSTE itself.Update2: Trying to add some slightly better pictures and others that show the MS Trackball Explorer, Logitech Cordless Optical Trackmall, and the smaller Elecom "DEFT" trackball mouse. But some pictures are not loading to the site. Sorry. :(Update1: IMPORTANT NOTE: Waaay down in the comments (the oldest one at the "bottom" should be a link to the Elecom software download page and the English PDF manual. As this mouse is "very new" you *DO* need a more recent Elecom proprietary software to recognize this mouse if you wish to use it's three proprietary function buttons (F1-F3).Long Winded Review===============This new Elecom Fingerball wireless mouse - the M-HT1DRBK - appears to have been released is June 2017 and has been available on Amazon since July 2017. In August I was about to order a second of the smaller Elecom M-DT2DRBKs when I stumbled over this new **larger** "HUGE" mouse and figured it was worth a try. The M-HT1DRBK just arrived and after giving it a ten minute test spin I just ordered two more. No clue if it will take "1-2 months" for the next batch to arrive, or if the price will drop from $85.99, but would say it is certainly worth the investment. FYI: It actually does say "HUGE" on the mouse itself. :)Comparisons to the MSTE (MS Trackball Explorer)======================================1) It has a nice large "red ball" like a certain MSTE we all know and love. In fact, the Elecom ball is slightly BIGGER than the MS one. There were many reviews about the smaller Elecom mouse's "grey ball" having issues, and several people purchased a "blue" M570 ball to swap with the "grey" one. From my quick tryout of this new mouse with it's "red ball", would say that the quality looks to be significantly better than that of the smaller mouse's "grey" one. An excellent improvement.2) This mouse is *MUCH LARGER* than the smaller "grey ball" M-DT2DRBK. Excellent for people with "larger" (aka normal sized) hands.3) It is a bit wider than the MSTE, and Elecom moved one of the three proprietary "Function Buttons" to the right side of the ball. If you use their proprietary software, this would give you "two buttons to the right of the ball" just like the MSTE.4) MOST IMPORTANT OF ALL. This mouse has a PALM REST. As this seems to be an alien concept to most mouse manufacturers I will state it again - this mouse actually has a place for the palm of one's hand to "rest" while using the mouse, so for the first time since the MSTE, there is actually a trackball that not only fit's one's hand, it is actually COMFORTABLE. Plus it doesn't have teeny tiny thumb-killing buttons like a certain L*git*ch Trackman. Wish I could show a decent side-view of the palm rest, but this can also be seen with via the pics on Elecom's web site.5) ??? I would assume that being a wireless device, there may be an occasional "lag" in response times, but cannot say for certain. However there does appear to be a wired version of this mouse as well. It's part number (August 2017) is M-HT1URBK.Usage=====Bulk of this review was written after only ten minutes of mouse use, so haven't had the time to give it an extended run, but observations so far are positive. "Weeks later" - Still great. Haven't tried the Elecom software yet myself (not using the F1-F3 buttons).- Seems to respond MUCH better than the smaller Elecom version (blue or grey ball).- Range seems to be about the same as the smaller one. About nine feet out it gets tricky and Line of Sight is critical.- The "left" button isn't as "tall" as the MSTE's, so my clumsy thumb is hitting the wheel, but this should be a minor issue.- ??? I read elsewhere that the "left" and "right" mouse buttons are "better quality" than the other buttons, that one should be able to tell the difference, that they should have made *all" the buttons "better quality", etc. Haven't noticed any difference between buttons yet. Too busy enjoying having a wireless mouse that actually fits the shape of my hand for a change.Customization - aka The Buttons========================So far as remapping buttons, "drivers", and support for various operating systems... Would assume this mouse works as a basic mouse in anything from XP up to Win10. You've got your Left, Right, Forward, Back and Wheel Buttons, plus the three Extra Proprietary Function Buttons F1-F3. Remapping the eight buttons and basic customization is where it gets interesting. Would assume one needs at least version 5.1.0 of Elecom's proprietary software to use/control all eight buttons. For now I am sticking with X-Mouse Button Control which allows configuration of everything except the three extra Function Buttons. Both programs allow for the use of multiple profiles for easy customization across different applications. Elecom's software (and English PDF manual) is available from their website. I will try adding possible links as a "comment" later as this review is too long as it is.Odd Future Issue (?)================Since the palm-rest is made of a "soft" material vs plastic, I wonder how it might hold up over time. Will it wear out? Time will tell.

I decided to give the Elecom Huge a try as my current Nulea trackball was having some minor issues with the scroll wheel as well as catching/friction on the trackball against the roller bearings, despite thoroughly cleaning and relubricating. My initial impressions of the Huge were good; the larger trackball felt more precise, and the ball tracking itself was very smooth. It didn't take long for the smoothness to wear off and for me to start noticing some ergonomic issues.First, I'm seriously disappointed that within days of use it feels like the rollers already need some cleaning and lubrication. I haven't given that a serious attempt just yet, but I would like to point out that I've had trackballs costing half the price as this one perform better in that aspect. There's also some other disappointments such as the battery not being rechargeable, no option for a wired mode, and 2.4G performance being a bit lacking when the dongle is not optimally placed. As far as I can tell, 2.4G is the ONLY wireless mode (no bluetooth), and while I generally prefer it for its responsiveness I'm experiencing signal issues that I never had with other wireless mice at this workstation.Next, the ergonomics are, quite frankly, horrible, and part of the reason I wanted to try this mouse was because I wasn't 100% satisfied with the Nulea's ergonomics. The Elecom causes me wrist pain in such a shorter period of time, and I can almost entirely boil it down to the way the wrist rest flares out towards the bottom. This effectively increases the height of the rest and puts more pressure/mechanical strain on your wrist and palm. By contrast, something like the Nuela mitigates that, and also is appropriately contoured to help promote a more neutral wrist position. I found that propping up the front of the Huge does help a little in my case (you can see a mint tin as a temporary solution in my picture).Finally, I will give Elecom a point for their lightweight customization software, and generally the click feel is good and actuation pressure is appropriate. The scroll wheel is alright, but I don't like the amount of force required to scroll-click and the added up-down movement (or left-right, technically) doesn't feel great and has limited usefulness in modern software. For example, in most programs it is excruciatingly slow, despite being set to the highest speed via the configurator.Overall, ergonomics aside, since that tends to be very individual, the Elecom Huge fails to differentiate itself from competing trackball mice in terms of performance, though the larger trackball and integrated wrist rest are unique. Connectivity and charging options are lacking, and the Huge struggles to keep up with even generic brand trackballs that cost half the price. I really, really, want to like this mouse, and felt that 3 stars may have been too harsh, so I'm rating it 4. Truly, it's more like a 3.5 than a solid 4. I would still recommend giving it a try, but I don't believe that it's going to be for everyone.
