 Nice try, but...flimsy, cheap, non-functioning... DONT BUYJan 11, 2011
By S.Ralphson
I read the mixed reviews on this product but decided to buy it anyway - I figured the price was so low, I was willing to accept some hiccups and work-arounds. But after fooling around with it for quite a while, I gave up and sent it back. It was useless. It really is a piece of junk, and here's why:
1) The wooden case fell apart - the packaging it was shipped in (from the manufacturer) was in perfect condition, which means (to me) the factory inserted a broken box into the package. If it had been damaged in shipment, I assume the factory box would have been damaged. I read several other reviews warning that the box would fall apart. It did. Seems to be not just bad luck with a particular order, but a systemic problem with the factory.
2) The nuts/bolts that hold the wrench together were loose/missing. I found a loose nut in the packaging and was able to re-assemble the wrench. I realize this is a super-cheap wrench, but I would hope it would break/fall apart AFTER I started using it, and not because of abysmal assembly at the factory.
3) The number/variety of pins advertised is incorrect; 2 out of 4 sets of pins were identical, which limited the types of cases which could be opened. Again, a factory problem. I picture drunk people on the line just grabbing a handful of random pins and inserting them into the package. Turns out the size/shape of the pins I would have needed were not included.
4) The pin sockets were not properly sized to accept and hold the pins. One socket would only release its pin when I forcibly pulled on it with pliers. The other socket wouldn't hold the pin at all; 2 of 3 pin sockets were so loose that I couldn't apply pressure to unscrew the case w/o the pins falling out.
5) The thumb-screws to adjust the width of the arms/pins would not adequately allow adjustment or tightening. As soon as I let off the thumb screw, the pressure released. I would have to hold both screws with my fingers to keep constant pressure; this was difficult since I needed other fingers to hold the loose pins in place.
So even if you buy this with very low expectations (as I did) for that occasional use once or twice a year, this is NOT worth the effort (even though the price is great). It just doesn't work. I plan to research and buy a quality wrench and not fool with this worthless junk.

 Can be made to workMay 26, 2010
By L. A. S.
"Thumper III"
Since the exact same wrench is sold by numerous vendors at $5-20, I got the cheaper one. As received, the exterior packaging was intact and undamaged. Both the top and bottom pieces of one end of the wooden storage box were broken free at the glue joints of wooden case and were loose inside the packaging. I re-glued the pieces to the box. The sets of pins that engage the watch case come in sets of three. I believe these are: Large round, small round, large chisel and small chisel. Both my chisel shape pins sets were the large size (no narrow chisel-end set) Because of the broken end of the wood case, one of the chisel shaped case pins was missing and had apparently escaped the exterior packaging in shipment. But I did get possibly an 'extra' set of the small round pins installed in the wrench. If I need a narrow chisel, I will try grinding down three of the larger ones and then use two large with one narrow for the large set.
The wrench itself was a bit loose. The side plates did not clamp the pin holder bases snugly and allowed the holders a lot of movement that could easily disengage the pins from the watch case in use and damaging the case surface. I disassembled the wrench and shortened the plastic spacers between the side plates, with a few wipes across sandpaper, until the pin holders were held just snug. While it was disassembled, flattened one slightly bent side plate with a couple hammer taps. Re-assembled, the wrench adjustment is smooth, the pin holders tight enough not to wobble and the adjustments stay where set during use without holding the adjustment wheels. Plenty good enough for non-commercial use. I am satisfied
This may seem a lot of work to produce a usable wrench, but writing this probably took longer than all the work. Making one from scratch would probably cost me over $30 in materials and hours of design, fitting and assembly. I'll make back the less than $6 cost of this item (prime 2-day shipping- no cost) the next time I don't have to drive 20 miles to change a battery (also available thru Amazon).
Should have ordered a case vise at the same time, but will probably just make a maple one like ASIN: B000RB1XNA .

It does the job.Dec 17, 2008
By pk pactogie

If you have an expensive watch, get a professional, otherwise this will do the job for you for all those occasions you need to replace batteries for your watches. Just be sure to snap the bits in the slots. If you don't snap them, you'll think the bits don't fit. Make sure the bits have a firm grasp before turning to open the watch case so that you won't scratch up your watch. It is what I've expected for 10 bucks.

 Poor qualityMar 28, 2011
By LG
Unfortunately the quality of this item is pretty poor. There's so much play in both adjustment mechanisms, I would hesitate using this wrench out of the box since you'll probably end up scratching the back when pins slip out of place. Another reviewer took theirs apart and sanded down the black plastic spacers. I ended up taking mine apart and adding some nylon and steel washers I had handy to tighten things up. Unless you plan on channeling your inner MacGyver to remove the slop or are willing to risk scratching your watch, I'd look elsewhere for a quality case wrench. Good luck.

Not for larger dive watchesOct 06, 2010
By R. Mayer
The tool itself seems just fine,and I like the idea of the 3 prongs, but it will not open large enough to fit the back of my Casio dive watch, which is the watch I bought it for. I'm having to buy one of those tools that just has two prongs, since that's what I've seen several jewelers use. If this one would open another 1/16th of an inch, it would have worked well, I'm sure.
