Review on GIYO Mini Bike Pump with Pressure Gauge & Repair Kit - Portable Compact Bicycle Pump for Road, Mountain & BMX Cycling - Presta & Schrader Compatible - 120 PSI by Saul Rivera

I bought 2 of these, one for my son's bike and one for my wife's bike. They installed in minutes. 2 screws that fit into the pre-drilled holes on the bike and a small velcro strap. That's all there is. I love that it comes with a basket/soccer needle and other related items, it comes with a tire patch and a tire removal tool from the rim. I didn't read well enough when purchasing as I didn't know it would come with extra stuff. So that's a bonus for me. I don't know if the sensor is accurate. My son's bike tires have been getting a little low lately, not sure why as both tires (tubes and outer) were only replaced 2 months ago. So it is not clear why they will flow already. In any case. Today I mounted this on the frame of the bike in case he keeps out with his friends and his tires lose pressure. I hope not. This is one of those items that is more for emergencies than everyday use. at least. for me it. Many Thanks.
