well ive never delt with them for anything, but i have heard bad reports, and have 3 or 4 myself
ive had 3 chargers previously that i have aquired, and on examining, one was half ported, 2 have had a "service" and left original bearings in one side
and the weekend just gone, cracked open a charger off a car i bought, same again, one side original vag bearing in there, and the apex seals they commonly cut them down as its too much effort to make them fit lol
obv cutting them down leaves big gaps at the ends, again not good
maybe they have changed who they employ now, who knows, but if my charger went pop and i checked and saw it had original bearing in, i would be pissed, and would seek costs from them, and legally you can prove it all, so you could even claim it all back im sure...
but i drifted a bit there
The thing with charger services is they give you a closed charger, you cant check it so its going off trust, and by my above comments, they seem to abuse that trust
What they should do is take pictures as they do it, but they wont, as they dont change the bearings lol
