LERA Mini Bike Pump High Pressure 130 PSI - Reliable, Compact & Portable- for Road, Mountain and BMX Bikes - Premium CNC Aluminum- Presta & Schrader Valve Compatible - Extremely Lightweight.

Great pump! I work at a huge office building where a lot of people bike in, this is perfect for us to keep in the office in case someone needs help. Its quick and easy too. Came fully intact so no need to worry about assembly! I'd recommend this to anyone who owns a bike..especially at the low price.

It is small, very small. But that's not the reason for my one star review. The inner rubber gasket started breaking just after the first use. Now it is having difficulty in holding the valve, pretty much making it useless.

Small, light and very nicely made. Attached plug to cover the output is a thoughtful touch. Not unexpected, it does take a lot of strokes to inflate a tire. Claimed Schrader and Presta compatible. Mine came set for Schrader with no instructions on how to convert to Presta. It appears what's needed is to unscrew and remove the output ring, invert the pointed part inside (careful not to lose it!) and the rubber seal inside the outer ring so that the small hole faces out. An instruction sheet, even simple pictures would have been helpful. Otherwise, it's a quality made device that's easy to carry for emergency flats on the road. One star off for lack of instructions.

Pump doesn't give a lot of pressure per pump, and the material quality isn't the best.

This is good for emergencies and for a travel bag, but a full-size pump is more efficient. Even minor pumping with this thing can take a few minutes.

Not bad for the price! The trick is to push it all the way into the Presta valve so every pump gets in the tire. It does take a lot of effort.

Listen, I'm a with-it guy (at least savvy enough to work a bike pump), but this thing is as useless as it is cheap. All it did was deflate my tires. Extremely disappointed with what I got.

Don't expect this to be as efficient as a floor pump... It's designed to get you home!! There is only a small amount of volume with each push.. it works and is able to get a tire temporarily enough air to get you out of the woods. It has a nice bracket that fits perfectly onto the brazons that hold the water bottle. Or it's small enough to fit into a small backpack or seatpack ....
