Five or maybe it was six, years ago they got caught photoshopping images (ineptly) to hide flaws in the pipes they were selling. The images were posted here with the photoshopped image next to the actual pipe. Things got a little, well, more than a little, heated, and I remember the thread being poof! disappeared as a consequence. There was no question that the images were deceiving, nor of the intent to deceive buyers.
Their record is mixed. There are customers who are very happy with them and there are others who despise them.
There are much less, ahem..., controversial sellers on eBay.
And there was probably good reason why the thread was pulled. 100% of the people aren't going to be pleased all of the time.
