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.

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!

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!

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.

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.
