This set of sensors works perfectly for me. I see no reason to give less than five stars. I have used this kit on a domestic heat pump and it has worked well, there were no leaks anywhere including the hose connections. Displays are clear and legible. I don't know the lifespan of the plastic handles but they seem pretty durable. The case is big enough for all my adapters. I like it at the moment! If I find any issues with this sensor set I will update it.
