LPS Rocks!

I reordered a 42" belt for an HP 500 plotter in September 2015, along with the kit to install. The belt wore out in November, 2020. I reordered the belt, and LPS honored the "Lifetime Guarantee" and refunded me the full amount of the second belt, no questions asked. Just a picture and original receipt. Thank you LPS!!!!!!!

Hi Mark,
The only warranty replacements we don't honor are for customers who didn't buy the LPS belt in the first place. I'm not seeing any contact from you in my database. If you have the original order number, please send it to along with a photo of the degraded belt.

If your smart, you will spend the extra money (compared to Chinese belts sold on ebay) and buy this belt for a direct replacement. Never have to replace it again. *****
