I purchased two Clamps and so far have used them to make 14 drawers for workshop storage and 5 picture frames.The vice clamps are deep for holding the material securely and the quick release feature in quite handy.
I have half a dozen of these clamps in my shop and I think they are decent little clamps.Being steel, they are very sturdy and I have found the spring/jaw tension to be excellent.Though I don't use them all the time, at times I find myself with a clamping need that only these clamps can satisfy.The only reason that I am not giving these five stars is because over time the rubbery-plastic tips on the jaws (that protect your work) tend to work loose and slide off.This can be a bit annoying.Other than that one minor complaint, these are good clamps that I have had a lot of success using.
I can't think of anything about these spring clamps that I'd change.I use them for woodworking to hold on trim (or whatever) and they do the job.
You might think a spring clamp is a spring clamp but after using a cheap Chinese clamp and it has has dented your wood project you might look closer. I have Pony clamps that are 25 years old and still working great. I just needed more for larger projects. The Chinese junk is gone from my shop. Don't waste your money.
I've purchased a total of three of these band clamps over the last couple years. I do a lot of curved panel work and they are quite handy for that application. The included corner blocks come in handy for those who do a lot of small-to-medium sized frames too. One problem is that the clamp body is made of plastic (the 'Y' section into which the screw handle inserts). On 2 of the 3 clamps I own, while clamping curved casework where only the band itself was used to apply circular clamping force (no clamp blocks were used), one or both of the plastic guides on the 'Y' section broke completely off the clamp body. I must admit that Pony was quite good about replacing the entire clamp when I informed them about this failure mode, but Ibelieve that the clamps have a limited range of application and should not be used in any clamping configuration where the band angle of entry into the clamp body is equal to or greater than the angle of the clamp guide's throat. For example, if you intended to band clamp an oval table pedestal of about 4' length and 1' width,with the clamp body located on the long side of the workpiece, you would run into the above situation (that is, incidentally, the application where one of the above-mentioned failures occurred). I believe that the product could be vastly improved if the clamp body were fabricated of aluminum, steel, or iron, instead of the plastic it is currently made from.
These clamps are the little cousin of Pony's great 3/4" pipe clamps. While the 1/2" clamps work fine within their limits, they do havelimits.Applying a lot of pressure will flex a 1/2" pipe, possiblyleading to an out of square joint.I also do not think that the clamptightening mechanism is as well made as on the 3/4" clamps, but it isstill pretty good.I have several of these clamps and while I think theyare a good value for the money, I would suggest spending a few more dollarsfor the 3/4" clamps.
I am very pleased with how well this little vise works. I make silver jewelry and this was one of the few vises I have found with smooth clamp faces. I use it to draw wire, make bends and hold pieces for detail work. It is solid enough for some heavy hammering-on, and the screw is precise and smooth in operation. A very well-made tool.
The cabinet claw clamps by pony are probably the most innovative kitchen cabinet installation tool on the market.These clamps make aligning cabinet stiles fairly simple with the perpendicular adjustment.They arevery rigid and can often be your only support when hanging wall cabinets. A nice feature is they come with rubber padding to protect the cabinets. If you do kitchen installations like I do,you must have these clamps. They are well worth the fifty dollars.
These clamps have been around forever and for those of us who are older than dirt they are like dear friends that we could not bear living without.I have several and will continue using them until one of us wears out. 
These clamps are great and no matter how many you own you will always need one more.To make them even more usable buy pipe that is threaded on both ends.Then you can use a connector to join the pipes together if you need a longer clamp.We connected five 48" bars together once to make a 20' clamp and used it to draw up the rails on a deck.
