OCS.tecOUT TANK WATERHEATER THERMOSTAT AQUARIUM FISH TANK AQUARIUM 16/22 T09

Cannot recommend this product, 16 mm pipe fits inlet & outlet OK, however both inlet & outlet were off centre & when you tightened the outer gripper nut which grips the pipes in place it does not hold them. Tried wrapping lots of thread tape around the pipe but didn't help. Going to remove the nuts completely & try jubilee clips. The unit does work but temperature gauge is around 4 degrees out. I should have returned the product for a refund unfortunately missed the return time-scales.
