I bought one of the 20 lb. Klingspoor bargain boxes. My experience was mixed.
The box contained only two grits, 150 and 220, which was very disappointing. When I re-read their ad I had to concede that they never promised more than two. Still, the picture and text was misleading, at least to me. OK, give them a D in marketing, from a customer's perspective.
The biggest and heaviest roll (7+ lbs.) was less than half covered with grit, leaving me with 3-1/2+ lbs of worthless cloth backing. Pretty disappointing and I decided to say something. They immediately responded and offered me a free 10 lb box of fine grits, which is what I really wanted anyway. I accepted and I had the second box within a week. It was perfect.
They took a little of the luster off of their response when they reminded me, again, that they hadn't promised me any specific grits. Well, I knew that by then, but I had expected <u>some</u> grit on all of the backing.
So another D for QC on their bargain boxes, which they really don't QC at all, according to them.
I will give them an A- on customer service. Would have been an A+ if they hadn't been so insistent on telling me something, for the second time, which had nothing to do with the "missing grit" problem.
They have good products and good customer service and I'll try them again but I'll be more careful next time. Maybe they will be, too.
