Review on 🚲 Mini Bicycle Frame-Mounted Air Pump Kit for Presta & Schrader Tires - Portable, Accurate Gauge, 150 PSI High Pressure Inflation - Suitable for Road, Mountain, and BMX Bikes by Michael Willis

Great design and concept but the product itself is really unreliable, used twice and the third time it just stopped working. Don't think driving with this device will let you down when you need it most. (The tip is broken, loose and won't let air out of the tire, tons of air just has nowhere to go when inflated, cheap locking system). Unfortunately I didn't succeed immediately after the return. Update: Support emailed me and offered a replacement/refund. The rating for efforts to fix the issue has been changed.
