MOSONTH Portable Mini Bike Pump - Lightweight and Easy to Carry Tire Inflator

tmichel: This pump is great except for one flaw. For presta valves, it screws directly on the the valve core rather than the outer threaded sleeve. When you finish inflating the tire and unscrew the pump, the valve core comes with it and all that hard work pumping vanishes into thin air. Make sure your cores are very securely tightened in the valve sleeve before attaching the pump. Even doing this I have managed to successfully remove the pump about half of the time. Makes for a hard trail side fix if you don’t have tools to tighten the valve core. Otherwise I can’t complain about much. It’s small, light and does the job most of the time.

JosephJoseph: I've had this for around 7 months, well within the 12 month warranty period the company (Mosonth) confirms in the original packaging and online.
It worked wonderfully (though slow, which is to be expected based on a hand pump this small).
It's small and portable, and I've used it for small tires on both my bicycle and motorcycle.

However, the stem completely snapped off after light use. I'm not sure how this could happen, since it's been 95% used for a bicycle.
At the time of this posting (1/16/2020), I emailed the company at the email address they provided (service@mosonth.com) on 1/5/2020, and have not received any response whatsoever.
If the company will stand by their warranty and replaces this product, since it did perform exactly as expected (when it didn't break), I would change my review and outlook to 5 stars, because proper replacement of a defective item is what we should expect from a reputable company, that supposedly has a 12 month warranty.

1/26/20 UPDATE: The company contacted me back and I was able to get another replacement for free under warranty.
Changed to 5/5 stars, A+ customer service!
Hopefully the...

Miguel: This thing is super compact and portable. I’ve had a lot of travel pumps, but never one this streamlined and unique looking. The gold model of this pump adds to the all around cool look of it. Easy to use and super effective. Fits in a small pouch, or even your pocket. Fits presta and schrader. It feels pretty sturdy, and like it will stand up to day to day use. Definitely happy with this pump. Highly recommend

John M.: My presta valve tires never worked with this pump but the size is definitely awesome. Is a little awkward to use and I bet if your tires aren’t weird like mine it’s a good backup carry around pump.

Sharman: I bought it for my dirt bike motorcycle. I don't like to wear a hot back pack full of stuff when I ride, so I wanted this small pump to fit in my fender pack, which it does very nicely. I did test it on my flat mountain bike tire. It works as expected. It took many pumps, and my arm was tired, but less than 2 minutes and I had enough air in the tire to get me down off a trail. 30 seconds more and I had 30psi. Maybe pair with some slime or a tube repair kit. The materials seam to be of better quality than expected so I hope it will last may years of age and abuse. It was nice not to lose air taking it off the stem, after pumping. I'm sure it can do a motorcycle tire, but I'm worried that if it requires to pump up more than once in a day, it will be too small to handle the inconvenience,,,,I hope I 'll never have to find out.
