Review on Enhanced Robinair 75260 Coolant Refiller Featuring Air Lock Prevention by Maurice Matlock

Bought because of the Robinair brand. Spent a little more hoping for a quality product. The device worked perfectly for three fillings of the car. In the fourth car, it was noticed that the vacuum cleaner was not working properly. When the coolant charge hose becomes immersed in liquid, it begins to suck it into the hose. The plastic valve did nothing. When the screw was removed from the small handle I found out why it wasn't working. The plastic shaft had snapped off the valve and the handle would not turn. Outside the return window with Revain and does not appear to be backed by a guarantee from Robinair. For a few dollars more than the competition, you could have used a quality valve. It's just a rebrand of a cheap plastic gimmick.
