The product runs so far but good (only a few months in operation). In between, I have noticed a drop in performance, this is but now resolved. At first I thought it was up to the pump, because after prolonged operation suddenly from the sprinklers barely came out what. I was therefore in e-mail contact with the customer and can Einhell me of these also expressed only praise. The answers came quickly and accurately. The problem was ultimately not in the pump, but in the pollution of water. Too much sand in the water has the sprinklers gradually clogged, so hardly wass flowed through.
About life I can not say anything and the first winter I also still in front of me ...
Addendum:
Now Four years have passed and I've gone from four stars down to two. I have the vacuum hose hung higher and thus no siltation in the water. Every winter the pump dismantled and stowed frost. Nevertheless, it has now set its service after four years. Something in the system is leaking. If you do not, the pump uses two days in a row, but the pressure drops in the system, the water flows back into the well and will no longer be drawn in switching. The pump works and works, but there is no water. Only if I manually admit water into the system, and several times, is again sucked water. So I can not work, because the pump is not in continuous operation. This is incredibly annoying! I have all the hoses and connections checked everything closely. The error must be in the pump. Another big problem is that there is no constant pressure is built up. Even after the silting was resolved, was this annoying problem. Just imagine, the pump builds pressure up to five bar and then turns off. If you have connected but a lawn sprinkler or spray hose, the pressure is very slowly lower ... and in time comes from the lawn sprinkler out less and less, and in the end it only trickles and the thing does not move before the pressure has arrived at 3.5 bar and starts the pump again. In a spray hose that's even worse. So, for the irrigation device is virtually unsuitable. I have spoken with many neighbors have similar pumps, all the same problem, now no one has a domestic water supply.
I recommend anyone who has the possibility of a pumpjack. Silent, invisible, constant pressure, must not be broken down in the winter, at low cost. Am now switched and currently very satisfied. Again, of course, the long-term test remains to be seen.
So who stay two stars because it was easy to install and published four years served its purpose. But negative outweighs now. Because the domestic water supply, has more performed their actual job, watering the garden bad than good in particular.
