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.

Easy to install! Great customer support!! First time on any power meter and quite interesting information! Super easy to install at home with basic tools. Just follow the oficial video. Great help from customer service to find out exactly which model did I need.

Must better than my order with a distributor I had a bad experience ordering the Shockwiz from a distributor (Jenson USA) and they shipped me a USED product instead of the new product I ordered. They also did not ship with the 2 day shipping they stated. It took weeks to get a refund. Quarq shipped brand new product, they got it out the door the same day and when I had questions their staff had actually used the product and was able to walk me through several things!

4/23/19 This has been my first order… 4/23/19 This has been my first order placed with Quark. The person whom I dealt with through the entire process is, Luke. I will say that my experience was nothing short of "world class" Luke provided amazing service, always followed up lightening fast, provides detailed answers to all my questions, and was truly interested in providing the best customer experience. It was a great pleasure working with Luke! Give the guy a nice $ bonus when you can. He is worth it. Mark

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.
