Great pump
Directions aren't the best (the direction of the valve grabber handle), but once my thick brain figured them out, it works like a champ, and I had zero issues mounting it. I don't come close to hitting it when riding so no worries there.

Can’t go wrong with Parktool
Works well and is of good quality. This pump is a bit larger than the micro pump and is ideal for bigger tires, but it is still lightweight.

Best of the best
Why did you pick this product vs others?: Probably the best miniature pump made

Came with a problem
I purchased this pump as back up for C02 cartridges on my gravel bike. It arrived in non-working condition. I contacted Park Tool and they sent me another even though I purchased it from a third party. It works, although I have not, thankfully, had the occasion to use it on a ride. Park Tool is very good with customer service, which can make up for the high prices of their tools.

Size and efficiency
Bought this after reading some product guides that recommended this as one of the most efficient pumps for its size. I concur that it is small, light and effective. The review (from Singletracks, maybe?) said it only took something like 3 pumps to go up one psi--I've found it to be more like 7 pumps in my 2.3 tires, but I'm happy with it. I specifically wanted a pump that didn't have a hose that threaded onto the valve stem, as these are notorious for removing the cores when you unscrew them (so frustrating). I can fit this pump in my USWE 3l pack if the bladder isn't full. I only take it on rides where I'll be out in the back country, and I still carry Co2 to seat the tire.

Missing pieces
Did not come with all of the mounting hardware.

Perfect size backup pump for large tire bikes
Installed this on my bike and immediately got a flat 10 miles from home. After patching the tube, I used this pump to get my enormous 3" tire back to the full 30psi in a perfectly reasonable time. There's no need to carry anything bigger. This does the job and doesn't get in the way. Would recommend for all bikes running large tires. You'll be glad you have it when you need it. This is probably not the best choice for skinny road tires running high pressure.

It doesn't work
It does not fill bike tires with air. Therefore it is totally useless.
