I fixed their generator about 10-12 years ago. Back then, there were few official, specialized offices. Then everything was fine and they were the best according to the reviews on the forums, but the device had to be brought. Now I have another car and applied again - cleaned, everything that needs to be replaced, warranty. But you don't need to take it off yourself - you came, gave the car back, took it off and put it on yourself. Well, big + fast. I hope it will last a long time :) I am very glad that such companies remain and do not lose in quality.
Good luck with your work.
It will be perfect for repairmen. You can find something that is not available in other places. They work professionally and competently. And the prices are pleasing. Outwardly, yes, it is not too attractive: gray, dirty, in a corner.. But still the advantages outweigh.
This is the best service, very nice and polite guys, they reanimated my generator, quickly and efficiently! Even the belt was changed, although they could not have changed it, I'm glad that there are such services! Good luck to you!
