I bought a DZero PM just over 2 years… I bought a DZero PM just over 2 years ago. PM spider integrated into a SRAM Red crankset. Super reliable up until it just died as I was cycling along. Phoned Quarq customer service and went through a few tests. Very polite guy confirmed that it was dead. Appreciated that it was out of warranty but thought they might be able to repair it or offer to replace the spider element at cost- No, no help or support whatsoever for an expensive bit of kit that had seen light careful use. Basically throw it away, zip all product support offered. Very disappointed.

Horrible Customer Service My Powertap hub, G3 cap stopped working. Tried to engage with customer service to warranty but since its been over a few years and i cannot produce a receipt although the serial number is quite evident on my photos that i sent i was turned down. Emails back and forth for 2 weeks to CS took days a time to get responses. When this was with Saris they would take care of their customers and i have used the hub based power for over 10 years, now Quarq and this is what i get, not even a discounted new hub cap unit. I have a new Tarmac that i was considering purchasing a spider version PM but i am seriously considering going with Dura Ace crank arm based PM rather than deal with this company.

Firmware DL failed, quick response but no help Can't fault their response but... Had a firmware download issue, contacted support and told 'it's dead' that was it! Fortunately a few searches highlighted similar issues with other products and all I needed to do was try a different ant+ dongle, really simple but nearly binned a few hundred £ of crank for lack of help!

Excellent service Excellent on-phone advice regarding power meter and bike frame/ group set compatibility. Quick delivery to Canada. Awaiting installation on the bike so unable to comment as yet on use of the SRAM Force AXS Spider mount power meter.

Quality Parts and Excellent Customer Service Items arrived and look good. I Will install them once the weather improves in New England. On a side note, customer support is excellent. They will patiently answer your questions so can be assured of buying the right parts.
