Review on 💪 Uharbour Pressure Connector Protector - 0 to 200 Psi by Jayshawn Cuatlayol

This range 0-15 is very inaccurate in the lower range. I tested it on exactly inches of water (27.7 to 1 psi). It shows 0 at 3 psi. It reads 3psi when it is actually 5.5psi. It reads 5 psi when it's 7 psi. I couldn't test above that, but it seems to have gotten better in the top half of the range. Besides, it's great. Update Edit: From 1 star to 5. So something happened yesterday. I press the function button and toggle between different types of measurements and voila. When he returned to PSI. IT WAS EXACT! It's accurate now, not sure what happened, but it's accurate to about 1/10th of 1psi now. To make sure it's working properly I'm going to test it from now on by blowing into it. I can blow 1 PSI with my mouth and it should read that. Before I inflate the wind rider.
