I will not repeat what so many other reviewers have written, but I do want to add my 5-star vote to this nifty little device. I use it for astrophotography, and honestly I could not be happier. A couple of weeks ago I set up to photograph the sun (yes, with special, safe equipment!), and I found myself running outside every 10 minutes to snap a picture (my goal - capture the changes in the sun over the course of a day). Needless to say, that got quite tedious after a while. After a bit of research, I found this clever little timer and immediately ordered it. Two days later it arrived, and on the next sunny day I set it on my Canon T2i to snap pictures for me...all day long!!! I went out every so often to check on it...thinking it would eventually have some unforeseen error. But no, it worked flawlessly all day long and dutifully helped me capture a treasure trove of solar images.Again not to repeat others in detail, but to add my votes...What I LIKE about this device:- Easy to use; despite a "manual" that is in broken english, it's simple to set up- Lots of timer choices: frequency of shot, length of shot, etc., etc.- It WORKS!- GREAT value! The *simple* bulb accessory from Canon is 2x more expensive and does NO timing, you could buy this for just the bulb button alone, forget ever using the timer, and pocket the savings or go have a decent dinner out!What is NOT to like:- Only one problem: it inexplicably has no On/Off button! So...if you want to save on battery usage, you must pull them out, store them separately, then re-insert them when you are next in need of a timer.That said, the display on this device looks like a low power user (there is a backlight you can tun on and off if/when needed), so I'm willing to bet you can leave a fresh set of batteries in there for a long time with no issue. But, I dutifully pull mine out to maximize their life anyway.Great value, great functionality, and it WORKS! That's what I wanted, and that's what I got.P.S. By way of safety, let me emphasize... NEVER look at or take a picture of the sun without the PROPER equipment! At worst you can damage your eyes, and you surely will blow out the electronics in your camera. If this review sparks an interest in anyone, be sure to do some careful research on solar imaging. Amazon (and others) sells equipment necessary to do this safely!

I bought this for use with an XSi as I want to try some time-lapse photography without spending a huge amount of money in the process... I'm not sure if this is something I'll "get into" in a big way.The device itself is pretty intuitive to set-up and use, in fact once I played around with it and figured it out I looked at the manual to see if I'd missed anything, and put it down thinking that if I'd gone to the manual first, I probably would have been confused as to how to operate it! LOL!I haven't had the time to go out and take a time-lapse sequence yet - land/cloud/starscapes are my area of interest - but I did set my camera on my desk beside my computer the other evening with the timer plugged in, and let it take photos at varying intervals all night; I think it was running for 5hrs all told and it didn't miss a beat. I used it on Manual and Bulb without a problem; on Aperture and Shutter Priority it worked like a charm, activating the autofocus each time prior to the shot being taken.The following should be of interest to those who want to utilize the Mirror Lock-Up ability of the XSi; if you do so with this timer, you will need to "take" two shots per photo needed for your sequence. This is because Mirror Lock-Up on the XSi is a two-stage process, the first press of the shutter lifts the mirror out of the way and locks it into position, and the second press actually takes the photo and drops the mirror back down ready for the next cycle. So, if you want to take a shot every 10 seconds with Mirror Lock-Up, you'll need to program the timer to take 1 shot every 5 seconds.In fact I've just bought a 7D and the Mirror Lock-Up is exactly the same as on the XSi, so I'm assuming this is standard across the board for Canon cameras; not sure about Nikon etc.For something this inexpensive the build quality is perfectly acceptable; I tend to "baby" my equipment and would expect to get a reasonable amount of use out of the product. Yes, the lack of an On/Off switch is something of an annoyance, but really, when it's not being used all that's being powered is the LCD display, and a couple of AAA's have got to be good for a year or so! LOL!Based on the fact that the timer works flawlessly, and its low price, this is an easy 5 Star recommendation!
