Works really well, only complaint is the antenna spring assembly is difficult to get a wrench on to tighten it up, when designing the unit they didn't allow big enough flats for a normal wrench to tighten it up. Had to use vice grips which I wasn't pleased about. However it does work well and besides that is a good unit.

The product worked  nice. The clips to hold the bar to the posts  kept slipping. I had to apply a vice grips to hold it in place. I would recommend this product to everyone.

Works great.  The hand grip tends to come out and needs to be pushed back in regularly.

Proved to large for my grip once installed and had to be returned - overall a great product.  The single button grip is the best product I've tried

VZ makes some fine grips, this pair I was disappointed that it did not come with any options I usually like to add like the thumb groove etc.

Works great except had to add some grip stuff as cabinet was smaller then clip so it doesn't stay in place

While this cutter technically works, I bought another with a curved handle as I found the straight handle awkward and sometimes bothersome to my wrist.

I probably should have used the larger of the two but with the smaller one having a long strap also, I thought it would suffice- for a 1.5" hand-gripped PVC connector. I felt like the rubber strap would snap and it took me a few tries to loosen it but it did work, albeit with a few scuffs in the rubber strap from the grip teeth slipping.

Preferred a solid unit that slides to adjust rather than one with holes and fasteners, but it does the job.

When these worked they worked well, but I mainly wanted them to help with the trigger grips.

Now I'm not what you would call a heavy gamer - I use the PS Vita maybe 2 hours every second week. That said, I was really disappointed when the right trigger on the grip began to stick. With the game I play the most (Need for Speed: Most Wanted) this means the accelerator sticks, which is a problem.

Otherwise this is a nice and comfortable small size grip for the PS Vita.

they do not look like the picture as everyone says, but they are good grips except to get them to fit tight
requires torqing in the screw so much it has to be shortened

Works well, better if you have a vise, I don't.

Awkward to use but works well.  You don't have to bend over or sit down to put a pair of shoes on, but can be clumsy.  The grip handle helps.

The vice works well with my family's Seiko watches.  It holds them well.  The wrench tends to slip out and I ended up buying a more expensive three prong version that has several different bits that fit the watch back slots better.  My watches are all water resistant so the backs are hard to remove.  If yours are not so tight, the wrench may work for you.  You can put the vice in a larger table top mounted vice so you can use both hands on the wrench.

If you are just a little mechanically inclined, getting a wrench, vice, and batteries will save you money in a couple of years.  The two wrenches and vice (two separate purchase) cost about $20 and a pack of 5 energizer batteries cost about $4.5 (I needed two kinds to service 4 watches) so after I replace 6 batteries I will have broken even in cost, plus didn't have to take the watches anywhere, but to my work bench.  You could save a little money ($7) by just buying the vice and the better wrench either separately or together.

The lever release is easer to use than the one on Vise-Grips, but there could be some other improvements.

I have two of these pliers, and both needed adjusting. On one, the lower jaw stuck out farther than the upper, and needed grinding back.  On the other, the jaws also needed a little grinding to get flush, and the jaws are offset side to side but I didn't correct that.  On Vise-Grips, the grinding is already done.

On the second one, the lever in the middle kept popping out of its groove, so I had to squeeze the barrel in a vise to correct this.  And the adjusting screw was bent, so I straightened it.  Works OK now.

With the modifications completed, these are decent tools, but aside from the release lever, I prefer the Vise-Grips for appearance, fit and finish, and a heftier adjusting screw (the newer Vise-Grips with the fast release lever don't work well).  And the Protos are pricey.  I paid $18.45 and $26.24 for mine, but would not buy another at the current price of 44.39.  The Grip-On GR11105  looks to be the same tool as the Proto, and is $19.90.

My aim with my glock 34 significantly increased with these sights over the stock, I give it 4 stars because I had to sand down the part of the rear sight for it to fit into the slide and it is not easy to install these if you do not have a vice grip
