JOMERLAN Mini Bike Pump and Glueless Patch Repair Kit, Tire Levers, Frame Mount & Ball Needle - Dual Action, Fits Presta or Schrader Valves for Mountain, Road or BMX Bicycles

Overall this is a good mini-pump. As far as I can tell, the whole thing is metal except for the o-rings and the endcap where the air comes in. I'm sure it can take a lot of abuse and heavy pumping. The capacity is pretty high for a mini-pump (less time pumping), and I've had no problem getting up to 100 PSI. Supposedly it's rated to 210 PSI, but my arms would definitely go out before then, and I can't think why you'd go that high anyway. The mounting bracket fits snuggly onto the waterbottle mounts (maybe too snugly, I had to ream mine my holes with a scissor before it'd go on), and doesn't block adding a standard waterbottle cage as well. Might be a problem if you had an oversized cage/bottle though.The people who're saying it doesn't work on presta are wrong. I've only ever used it on presta tubes and it's worked fine every time. I suspect that either they received defective models, or they weren't following the instructions correctly. You have to screw the head down over the presta stem pretty tightly, but on mine at least, once you do it's not going anywhere.Downsides:Heavy/Bulky- it's robustness and capacity comes at a price. Definitely not something you'd want in your jersey pocket, use the frame mount. And if you think a few hundred grams is the end of the worldNo dust cap- There's no way to protect the nozzle from dirt and road debris. You can mostly clean it out with a q-tip though, and I'm thinking of putting a little aluminum foil over it.Awkward mount- The mount can hold the pump two ways. Either holding onto the handle end with the thicker, valve end up, or holding onto the valve end with the pump end up. The clip holds much more firmly to the thicker end, but mounting it with that end down means that even more grit ends up in the valve. It's also held entirely by friction in that orientation, since the thinner end is above the thick end. Holding it by the thick end, with the thick end at the top results in the pump opening and getting in the way of pedaling, as well as exposing the piston to grit. So, I've mounted it with the thin end down, where it would be very difficult if impossible for it to slip out (although the pump does extend slightly sometimes, the roads around here are pretty rough and bumpy so I'm not surprised, and in no way could it escape). The clip doesn't hold this end as firmly though, so it rattles around a bit, I ended up putting some electrical tape right where the valve hits my seatpost, since it was starting to chip the paint a little. All that being said, the mount does it's job.Also, if you're pumping up to high pressure it's easy to accidentally cover the air intake, but that's less of a downside and more a thing to be aware of.

Is a good little pump I love the fact that come to all the extras it's a little pump up to over 90 pounds of pressure I use on my trikke Wheels the recommended to be used between 70 PSI and 90 PSI if I have to see a drawback would be do you have to screw it on the threads to use it instead of some type of quick release drawback is you lose pressure when unscrewing but not very much I find the over pump and then by the time you take it off you're at the correct pressure you need but the tire changing tools that came in real Handy already and the glue free patches and a nice little racket to put on the bike so you always have your pump makes it very handy I do recommend buying this pump well made small little package no rattle as you're riding

This bike pump is very well made. The pump works great for both balls and bikes. It far exceeds any pump I have bought in the past. The size is perfect for storage. There is no plastic that I can tell used to make this pump. So, hopefully this is the last pump that I will purchase in my lifetime. I only gave it 4 stars because if you want to pump up any thing larger than a regular bike tire, you will get tired. Pump is not very big.but that is why I bought it, tired of over sized pumps that fail.

Easy to use with presta valves, robust, compact, very sturdy, a bit heavier than some other pumps, but still light enough. Inflates the tires on my road bike much faster than some other pumps I have tried. The first pump I received didn't work quite well, I sent it back, their customer service rep contacted me tight away asking for detailed feedback and he sent me a new pump including detailed letter explaining how to use and appologizing for the inconvenience. Great customer service, they stand behind their products, buy with confidence, you will like the pump, if you have any issues, they will make it right.

I have had the pump for a couple of weeks and it is great. Feels durable and is easy to use. I have used it for a Presta valve and with a ball needle and it worked well. Once you do it one time, you see how easy it is to switch from the valve types.Jomerlan (I had never heard of before) appears to have good customer service, but I have not had a problem. They sounded genuinely interested in an honest review.

works great. used my first patch recently, took about a day to fully seal but im back on solid tire pressure. Neat bike frame mount for the pump. No pressure gauge but for the price this was a good buy

Bought this to replace the one we had that no longer works. It's small and is great to have on the bike in case there is a tire issue.

So far I love this pump, especially the double action. And I also loved the fast delivery.
