U4 Pro+ Plus Titanium Carabiner, Hidden & Dual-Bit Screwdriver | EDC Carabiner Multitool with Security Set, Heavy Duty Key Ring Holder, Utility EDC Gadgets for Men Outdoor

Really nice product. Great quality. Action on all the moving pieces is really smooth. I thought the key ring would be a little bigger but it still works great. I like the way the key ring is set up to keep your keys in place even when you open the carabiner. Locking mechanism on the blade is also excellent, and was really nice to receive replacement blades with the product.

Five star review. This is a very neat gadjet and has practical usage as well and works great. Lots of functions, it can hold a few key rings, has philips and flathead screwdriver bits which are also the same material and precision cut with very fine details. The scalpel knife function is extremely sharp, use caution, my poor friend cut their hand badly from it but it's better now anyways has a safety lock button so it wont retract or activate unless the button is pressed. The product comes with extra razors and a nice plastic box and cards. It's what you pay for and definitely a premium multi tool. Remember, use caution with the scalpel. Great product.

Feather light, smooth mechanism, the baled is safely locked away yet very easy to access. I have used this so much, and barely notice it's on my key ring. Not cheap but this is a quality product and worth it.

Pros: 1) Multifunctional carabiner with very useful tools especially built for EDC. 2) Sleek design and tough built. 3) Great EDC tool Cons: 1) Only con I found is that the opening is a slight small given that you are using it on jeans. The jean straps are slightly bigger and hence when putting it on jeans becomes slightly confusing. Not a major drawback but this issue can be addressed in the next version. 2) Price is on higher end, compared to other multifunctional tools. I personally found it very useful and would buy again if available cheaper. Definitely recommend this carabiner. Will post an update after few months to see how it holds up.

04/08/2026 I'm updating my review from a 1 start to a 4 star due to the sellers stellar customer service. The seller contacted me and offered me a full refund for the defective product. While I believe the product is still unsafe, the seller's customer service made a huge difference in my experience. Thank you ------------------------------------------------------------------------------------------------------ I wanted to love this product. It worked perfectly as a keychain clip and the build quality seemed solid at first. But after less than 3 months of light use (the hinge was opened fewer than 10 times, never under any pressure), the hinge failed completely. The screwdriver arm fell out and was lost, and as a result the blade arm is now unlocked and swings freely. That means I was carrying an exposed, unguarded blade in my pocket without realizing it. That's a genuine safety hazard. This isn't a wear-and-tear complaint. The failure happened well within any reasonable product lifespan under minimal use. The hinge is clearly a structural weak point, and when it fails, it doesn't just break the product, it makes it dangerous. I'd caution anyone against carrying this in a pocket or bag where an unexpectedly open blade could cause injury.

I'm a big fan of the RovyVon their products all feel and look like quality. Size wise a bit bigger than what I expected but acceptable as EDC. Weight feels so light you would think it's aluminum but it's not. The most important thing is that they put small locking mechanism for the blade and the bits. That's very impressive that they thought that far ahead. Super impressed with it.

It’s an okay product. I do not believe it is worth all the gyre or price. The extra tools were rarely used. If you carry a SAK or any other multi tool, you do not need this.

Extremely lightweight. You could wear it on a badge lanyard and never even notice it was there. The spring action is solid. No lose bolts. Blade and screwdriver bit pivot easily. Convenient size, and a clever design. The 2cm long ruler is cute, if not entirely useful. Scalpel blade is sharp (as all new scalpel blades are). Just wish this item wasn't so expensive.

This carabiner is excellent in every way. Being built from Titanium makes it extremely light and stong. The spring mechanism is first class and won't let you down even with extremely heavy usage (50 - 100 opens per day, 5 days a week). The bit driver is compatible with high end Leatherman Multi Tool bits (which I own) so I can customise it for a PH2 and S2 which is what I use daily. The little knife (scalpel) for me has very limited use but it does work and having replaceable blades is a bonus (it comes with 5). I highly recommend this carabiner anyone who wants a super lightweight carabiner for heavy usage.

This thing is awesome. I am always in need of a small knife to open a box or cut some thread or what ever that could use a knife but didn't want to carry a pocket knife. This was perfect, I got a carabiner that had a knife and screwdriver in one. I don't need to have additional things in my pockets. It holds my keys well, they have never fallen off. I clip it to my belt loop, never had it unhook. The knife and screwdrivers have come in handy the day I got it. I would Reccomend this 100x. Bonus, it looks nice too, unique design, different, and not flash.

Another very small but incredibly versatile and useful tool that is in my EDC kit. Many uses, strong and feather light, it also comes with spare blades. Great quality, great design.

Well designed and made, very light weight but strong, the extra tools are very handy and work well

Product was exactly as described. Functions great and looks cool at the same time. The small blade is great for everyday tasks like opening envelopes etc.
