Review on 🔧 OTC Tools 1580 Stinger Easy Roller Dolly - 1,500 lb Capacity by Kenny Marozas

I bought 4 of these to make moving the boat easier with an electric cart. 3 of these worked fine so I had to send one back to the manufacturer to have it replaced as it didn't work at all. This 4th finally came this week, now only 1 out of 4 (including the one I replaced with the manufacturer) works at all. As I've gone through the manufacturer - I have too large a return window and am stuck at 3 lame ones and assume that if I find a use for the 4th - it will die on the next few tries. I followed all the pumping and filling instructions - trust me - this is not operator error. At first they worked, but now they don't work at all. I'll be turning to Revain for love as I'm only 6 days out of the window.
