This is a really good little hand pump to have in your backpack or strapped to your bike.Pros:- Easy to get the hang of it- Pumps a surprisingly good volume of air pretty quickly- Pretty solid build quality for the price- Compact, looks cool and is a lifesaver for the moments when you're on the road and need something fast and ergonomicCons:- Can be a little confusing to figure out at first due to no instructions being shipped (at least with mine)- Can sometimes be awkward and difficult to use if the bike isn't perfectly stable- Build quality definitely feels like the usable life is only going to be around 50-70 full tires- I have to baby it a little bit to keep it from overheating and melting the cylinder sealsOverall, totally happy with it considering what I paid. It's a great thing to have around and does its job well, just be easy with it and it will perform longer and better. It's all plastic and it's not exactly what I'd call robust, but it's definitely not a piece of junk.4.7.24 - UpdateHad this thing and have used it to fill well over 100 full tires, the logos have almost worn off the handle by now and it still feels just as sturdy as the day I got it. This pump was well designed and well made, I recommend it highly.2.14.25 - UpdateI still have this thing, and it still works. The folding handle snapped off so I screwed a piece of wood onto it, and the thing still is going strong. I use it to fill up my tires at least once or twice a week. Whoever designed this definitely chose the right materials for the internals.

I purchased this to carry on my E-bike. I thought it looked a bit cheap and had low expectations when first received. But what the heck, I might as well try it. The first time I had to add some air I was pleasantly surprised how easily and quickly it brought the tire pressure back up. The big test came when I had to patch a tube and had to completely inflat the the tire from zero. It passed the test as I was able to air up and on my way quickly and without feeling like I had a workout from such a small pump. Mounting it to the bike was easy, and removing from the mounting bracket and replacing after is a snap.

I didn't figure out how to use the presto part of the pump, but I have an adapter for the one tube that has that style to get back to a standard. I reserved the 5th star for if the pump would have filled the tube/ball/etc in both the in/out stroke directions. It works great, it just require more pumping with it only filling in one direction. I like it, and recommend it to others in need of a small, lightweight option.

Best pump ever! I've had mine for a few years now and it is designed so well and easy to use. Great value for money.

Perfectly portable and works great

Update: Manufacturer sent me a new pump even though the damage happened just after the warranty window.This pump seemed great until it broke after just a year of relatively light use. The head component is attached to the shaft by weak glue. Of course i had no way of knowing this until it spontaneously detached and became completely useless. What a waste.

For me, it's a little to small.

I ordered this pump because I've used a zephal pump for 50 years and it was in my storage unit on the bike and I don't know if I lost part of it but the part that pushes the valve damn was missing so I needed a part so I needed a pump in a hurry and I saw this one and it was affordable but my other phone and it works but it won't open it out when trying to fix it so I thought for the money I'll try it when you finish working on a bike I needed that new energy but no pump. I'm in a independent living home and I'm on my own so all the stuff that I had for bicycles is in storage somewhere. So I was well pleased with this little thing at work great I would recommend it hotly it's worth it for the price which is very reasonable. That's all it works great for as little as it is well designed I would buy again. Thank you good night
