Not good for Presta - removes valve cores
I've used this six times, and three of the six, it has removed my valve core... This was on two different bikes with different tubes (one mountain bike, and one 700cc road bike). I think but am not sure that in both cases my tubes were Conti (Continental) tubes. I don't know why they actually make inner tubes with removable valve cores, but many (most?) inner tubes do have these.This pump seems fairly well-built (for the price), and is basically a copy of the more expensive Lezyne or even the Pro Bike pumps. The devil seems to lie in the details however. It's tricky to get the pump screwed on to the Presta valve, and if you don't get it 100% straight - if it's even the slightest bit off center - then what can happen is when you go to remove it, it actually unscrews your valve core and - poof - all the air comes out of your tire. I think the issue is that the connection is machined pretty cheaply, and so it's easy to get it on a little crooked. Combine this with the fact that inner tubes are manufactured pretty cheaply as well, and those valve cores are not always 100% straight or 100% tight either, and you have a recipe for this issue to crop up.I was able to get my valve core back in, but lucky for me I was doing this at home and not out on the road. Because I needed a needle-nose pliers to remove the valve core from the pump. I would not have a needle-nose pliers with me out on the road.One possible workaround is to make sure your valve cores are tight all the way in your inner tubes before you use this pump. The problem is that most people who ride with inner tubes have never even heard of a "removable valve core" and don't know what that is, nor have a tool for it. I ride tubeless on my mountain bike, so it's not so much an issue for me, I guess, now that I know that this is a potential problem. However, the 3rd time this happened, I was already aware and did think I was being careful and it happened anyway so I'm pretty skeptical....

Good quality for the money
I'm kind of surprised to see a good quality for such cheap price. Came complete with repair kit, mounting bracket, needle for balls, and even a hex key tool. What I like most is the hose extension to give you more room to plug in. Very nice and compact and totally worth it.

Very small pump !
This pump is very solid and seems well made . The frame attachment holds the pump rock solid on the bike , the drawback is the pump is so small that it takes dozens of pumps to raise the pressure a few psi . You can easily squeeze the skin on your hand painfully if you're not careful !

No suitable for tubeless, removes valve core
Use on Presta use requires to thread the pump onto the valve. One a tubeless setup, where the valve core is removable, the valve core will at least loosen if not be removed when you remove the pump. Note, valve cores should not be over tightened, so that is not the solution. If only ever want to use on tubes, without value cores, then it works okay.

Good quality and works better.Easy to use.
Got this pump a couple for my road bike,it is small and portable,attached to the bike.You'll never lose your pump again.Tested just now for my road bike which is so easy and efficient,this pump handles this without any problem,it's easy to pump bike tires.Overall this is an awesome little pump,but better than some of the larger pumps I have used.

A Hazard to your image, but useful.
Thought I'd give my bike some air. Turned my back to the street and pumped away. Turned around to some weird looks. Still not sure why. Filled my tires though 5/5
