Nice pice

Very helpful

Excellent Product

Very bad product

I have used this product for ~one year. It is a good product overall -- battery capacity and charge retention looks good. I used it multiple times on the road, to inflate my bicycle tyre tube, on the road, plus at home. Very handy/useful in that regard.However, 2 negative points --* The product info shows a max pressure rating of rating of 150PSI, but I have been able to fill only upto 90PSI. Since road bocycle tyres with 23-25mm tyres, need ~120PSI pressure, this pump may_not be able to go upto that pressure.* Recently, the pump flow on/off click button at the rear, was_not working consistently, and finally seems to have stopped working. I opened the rear cover and checked; the electrical and mechanical parts/connections look good. I am guessing the actual button has gone bad. (The 2nd photo that I have attached, shows the rear on/off click button, which has stopped working.)Disappointed that such a useful product has stopped working, due to on/off click switch issue. Another torch that I have, also stopped working, because of some on/off click button issue. So looks like the on/off click button mechanisms need to be lot more reliable; otherwise, the product becomes useless, even if everything else is fine.Since this was one of the first such products I found, which seemed quite innovative to me, I am still giving it 3-star rating. At present, more such products seem to be coming in the market (one from Xiaomi, which is a reputed smartphone brand). So if I were to have this same experience with a product which I bought today, I would probably give it a 2-star rating; maybe even 1-star.
