Review on DNM Bicycle Shock Portable 300PSI by Erick Bowers

I'm not sure of the accuracy as I couldn't measure the pressure compared to other pumps. I have found this to be fairly stable as I can make changes to my fork and then circle around the block and it will still show the same pressure. This sequence allows me to make small changes that I notice while driving. Changing the pressure is easy by screwing it in, pumping it up to add air, or pressing the bleed valve to release the pressure. The bleed valve wasn't too sensitive either. All in all I thought it was good value for what I paid (the local shop asked twice as much as the other brand).
