Review on 🔋 Xiaomi Air Inflator: Handheld Electric Car Tire Pump with LCD Display and LED Light - 150PSI, 2000mAh Battery by Jake Powell

Functionality and design is a good product. The problem I have 2 days after closing the return window is the following. The yoke that bolts the end to the Schrader valve is in two parts. It's a swivel, so the end can pivot independently of the hose. The first problem is that it's very tight, it's almost impossible to unscrew it fast enough without releasing at least 2 pounds of pressure or rotating the hose AND pump assembly. It's annoying and very inconvenient, but once you know that, you can just pump it back up and then deflate it to compensate. This is of course a credit to the Autostop feature and the hope for some accuracy. Now I've only used this on bike tires that haven't had any issues. Today I patched a nail hole in a radial hose and when I used this pump to increase the pressure to the desired psi, 33 lbs, the cuff started to leak badly at an erratic 15! The pump is now completely unusable. I will contact the seller/manufacturer and hope for a replacement, although my hopes for a second product are a bit slim. If I'm declined, I will dispute my credit card charge and both Amazon and the seller will lose. I would recommend not doing this until I have found a workaround with the manufacturer or seller. UPDATE: The seller was unstoppable. out and trying to contact the manufacturer directly was a waste of time. I'm done, Revane came to the rescue and accepted the refund and got my $ back. My search for a good working pump continues.
