The filter performance is good, the price at Amazon beat (the local retailers calling 120, - Euro more on !!) Quietly she is even, but after a week the function was extinguished. The casing of the timer is not tight so that the electronics has given up. Since I had no desire in fine weather, to disassemble the unit again and be sent for reclamation (The building has been used well over an hour) to be seen and the waiting time for replacement, I have expanded control and shorted the pump. (If another reviewer already described) - Now Playing once you plug in the connector. One should know this but what you're doing.
Without RCDs in the house fuse box anyway NEVER !!!! into operation.
Conclusion: If I had the local dealers to 289, - bought, I would have been really mad; I would have put the part on the counter as a whole and How does it move without replacement pump from the store ....
