Needless to say, I sold it BNIB and went with a crank based PM.

I have had a number of SRM's - both wired (2*SRM Pro's, 1*Science Track, 1*FSA) and wireless (Dura ace 7800 on the TT bike and 7850 on the CX).
All were bought second hand and all have all worked flawlessly!
Only issues I've had over the years:
- Sending coil on the wired SRM Pro damaged on the return flight from the USA. SRM Oceania fixed for free whilst replacing the battery.
- Solder on 1 PCV failed from removing the cable too vigorously. Fixed locally.
- Chainring bolt hole cracked on the FSA road unit which was unrepairable. SRM offered a replacement wireless spider for a great price with no questions if I was the original owner, but I bought the 7800 for an even better price.
Chain ring bolt holes can crack over time.
Hysteresis of the glue bonding the strain gauges can sometimes occur.
A couple of my older wired units are low 4000 serial numbered units (not sure year of manufacture but thinking must be over 10 years old) and are still going strong!
Contacted Quarq support, we did some troubleshooting via email.
After that, they sent me a pre-paid shipping label, I sent it back. Since they no longer made that model, they sent me a Riken PM brand new, and calibrated it with my QRings.
Process took about 1 week, and that was mostly shipping time.
Quarq customer services is amazing...hands down, probably the best customer service I've experienced. I mean, who replaced a used PM with a new model and pays for shipping ??
Won't buy anything else.
I bought a Quarq new, and I went through three warranty replacements before I gave up and got an SRM.
My PowerTap lasted about 5 years before the torque tube went.
I'll soon be selling a used (only by me and only for a few months) powertap 29er wheel. Not meaning to flog it here, but I would expect it to be just as accurate for the buyer as it has been for me. I only replaced it because power2max had the prologue deal for the new NG power meter which I took advantage of since I was converting NG to a 1x set up and needed new cranks anyway. So ended up with an S-type for the 29er and the NG will go on the road bike when it arrives.
Used doesn't necessarily equate to broken/defective or abused.
