Robertshaw Infinite Heat Control Purchased a Robertshaw branded model for a 50 year old Presto Quartz Oscillating Space Heater. Beautiful fit, beautiful price. Don't let price gauging at other Websites dog you. PartzStop is Best in Show.

Placed order on Saturday arrived by Thursday Placed order on Saturday, received items on following Thursday. Parts are OEM and shipped intact. My only detraction is that they notify you as "shipped" when the shipping label is made, which was a day earlier than when it actually shipped. Their price was noticeably lower than others, including Amazon.

PartzStop cancelled my order. No reason given. No answer by phone/email. Don't deserve my $$ I placed the order for a tool and paid via PayPal. The payment was processed. I later found out, via email, that the shipping label for the tool was cancelled and my PayPal account credited back the money. No one at PartzStop ever advised me, by email or otherwise, as to why my order was aborted. Attempts to contact PartzStop by telephone were met with a busy signal. No response to email. No return call after leaving my telephone number. Pretty pathetic.

UV light systems Ordered 30 Apco mag 11 uv light systems for our HVAC company. They were all in stock and were delivered fast, two days. Now my technicians can go out and start selling, otherwise it would have put a damper on our business. Would definitely recommend using this company.

Received part promptly Received part promptly; however it was wrong model. I contacted them and they quickly sent out correct model and gave me a prepaid label to return the other. I will order this part again as it is much less expensive than buying the OEM filter from our A/C company.
