The slot for the pin was too small so I had to order two just to get parts that worked

The watchband is nice enough (4 stars), but it came without the pins to attach it to the watch (- 1 star).  The previous watch band I had had pins with small "knobs" on them with which the spring could be compressed for removal.  These would not fit in the new watch band.  Fortunately I was able to cut those knobs off and reuse those pins.  But what a nuisance!

Seller was prompt.  Price was right.

Unfortunately the bolt slots were too small. My foot board bolts are 5/16". The slots appear to be 1/4". Also, one of the brackets was bent which I can't imagine passed any type of quality assurance check. The metal is thick so it had to be a manufacturing issue which is why the low rating. Otherwise it looked good and would've worked.

The connectors are not bad, but the pins are too large to fit in a perf board with 1.0mm holes.  I have to take a drill bit and drill out my perf board in order to put these connectors on it.  It should have listed the pin size.

The case does not allow sufficient space for the standard 30 pin plug to be attached at the bottom. I had to cut away portions of the plastic to expand the opening so it would allow the plug to make a secure locking snap into the 30 pin socket.

Look to be very nice quality. However the pin is not 3/4" diameter.  I had to enlarge the hole in the mount for 7/8" pin.  I wish the customers who answer the questions would give the correct answers or not answer at all.

I only bought it for the piston rings and piston, inner space for bushing and wrist pin was too small :(

I've had this a very short time and it already won't work.  I ordered it for a CF card.  There is just enough wiggle room that the card doesn't fit exact and I'm guessing the pins bend because now after less than 10 uses, it will not work.

Not quite 3/4" (so, shy of the stated .8"), and has to be about the smallest safety pin out there, which I've never been able to use (doesn't go thru the thinnest fabric and my fingers which are on the small side, have difficulty handling it).  If you want this size, check at a dollar store.

I had to cut a slot in the die in order to allow it to expand a little bit... It seemed that the ID was smaller than the shaft that I was trying to re-thread.. I was able to fix my threads and cut new threads after the slot was made. Other than the ID being tight.. It worked as expected.. I would buy again if I needed one.

It arrived, but the extra pins have no storage space, and I'm not sure how to change them. No instructions arrived.

These pins are really small.  I wanted the for big speaker stands.  Sadly I didn't return quick enough so I still own them.
Anyway, they are made well just don't be mislead by the size.  I think they should but a quarter next to it in a picture.

The design has a flaw, the pin that sits in the brake lever does not go in deep enough. It locked up my front brake.

only had 2 pins and I had to get the correct screws for my vortex venom. Works well but for the price you have to nickle and dime over the small part-WTF?

No way is this pin 3 inches long. It's more like 1 1/2 inches. For the price, it would have been fine, but don't lie about it.

Can't charge the Phone with the case On because the hole in the case is too small and avoid the Usb port to fit in the Phone charger pin

Too many "oversize" or "large" pins and not enough of the smaller pins.  Some have a "barb" on the insertion tip and won't go through material.
