Wendry PC Water Cooling Indicator, Replacement G1/4 Threaded Water Cooling Indicator Meter Indicator for Computer Water Cooling System

Pretty much a silly little doohickey item for the water cooling system. I installed it vertical and could see it spinning. Otherwise just an optional piece.EDIT: Okay the spinning fan in the indicator has stop working, pretty much if you are replacing the coolant in your PC, then you will need to replace the indicator as well. Given it's a $20 piece, well, up to you if you want to spend that money each time changing the coolant, of course that's like every 6 months to a year anyway so otherwise, my review and rating stands.

It stopped spinning after a month.I've even increased the flow rate of my loop, but it no longer spins.Maybe it only works properly in a vertical orientation?But if that's the case it should state clearly in the instructions.Update:My water flow rate has more than doubled since I removed it.NOT RECOMMENDED until waterflow issue IS resolved.
