Just tried to get a warranty replacement of a defective cylinder with many obvious chrome plating voids in them. After stalling me, using their ridiculous canned response of "try it out and see", they finally said I should ship them the saw so they could see the problem! An obvious ploy to illicit a negative response so they would have an excuse to deny warranty.
They even lied about shipping the large order I placed with them that the cylinder came in. It did not show up in the system for 2 whole weeks, until I told them I would ask PayPal for a refund, then it got shipped out the next day!
Avoid these lying thief's, order your parts from ANYONE else. Their defective part warranty is an outright lie, the majority of their parts are sub-part at best, and some are downright unusable garbage. I now join the ranks of many dissatisfied customers here on this site, and refuse to buy any more product from them. I hope you do the same.
