Unfortunately, the device is not intended for long-term use (-> planned obsolescence) and went with daily use after one year broken by Infiltrated water. Only the battery power dropped significantly and 1-2 weeks later it could no longer turn (charging LED was still working). After opening, the full extent showed: the complete interior was filthy with water, corrode the batteries and parts of the board, the engines showed rust. The water penetrates probably a by the subsoil or the motor axis sealing the air compressor - there are also many other (apparently) poorly sealed into question ...
By the way, the barbs of the nozzle cap wears off after a few months, even if you rarely off him and been attached so that it eventually has no support and must be changed, but that's just a small flaw.
Conclusion: Actually, the best mobile irrigator, but the quality of the seal is the question. One has to expect that after about one year pending an initial purchase ...
