Plain and simple Quarq is the best I have had a Quarq power meter for the past year and it has been wonderful. I did have to contact Quarq for a problem that I was having that stop me from using my device but made it aggravating and they were quick to respond and had great information that helped me troubleshoot my device and get it working perfectly. I could imagine using another power meter on my bike.

Great Power Meter, customer service and ease of install! Having not been very satisfied with advice on Quarq power meters from a few Canadian bike shops, I called Quarq direct to determine which set to go with. The guy I spoke to was exceptionally helpful and checked into my bikes specification to match me to the right Quarq. He even gave me a “watch out” for the chainrings that I run when switching out. Placed an order direct with Quarq and received within a week! Only negative would be the packaging could be a bit more secure. When received, the cranks were not in their holders within the box and we’re loose so would have rattled around inside the box. All installed, working perfectly on the indoor trainer and now to wait for a warmer day to hit the road!

I am pretty impressed with the Quarq… I am pretty impressed with the Quarq team and their willingness to carry the ball on problems. I have PowerTap pedals which have been far from trouble free. The most recent issue is after not using them for 8 months the cap on one pedal was frozen and would not come off even using semi destructive means. The Quark team happily took over..... As to PowerTap, I think they have caught a break. The cycling community has fairly low standards for vendors and quite honestly, their reputation was outsized IMHO

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

Outstanding customer service from Quarq… Outstanding customer service from Quarq tech rep who answered pre-purchase questions I had and then placed the order for me. Quarq DZero for Specialized arrived on time and I had it installed by my LBS. I've only had a chance for a short test ride so far, but I am very happy with the power meter. It connected instantly with my Garmin 520 and 920XT, responded immediately to power changes and also saves some weight over the P1 pedals I had been using on my bike.
