The baby oil works like a champ.
I always see folks dismissing the Vectors in favor of the Assiomas, but those have issues as well. I’ve been 90% happy with my Vectors, and the customer support I’ve gotten from Garmin on this product has been superior compared to Wahoo and others. If I were considering a power meter pedal, I’d be fine doing the Vectors again today - especially now that they’ve had 18 months to work out the kinks - or perhaps the PowerTap pedals myself. YMMV. I would be concerned about customer support as a US customer for the Assiomas.
My first pedals, I had the battery cover issue which was resolved quickly and easily, with minor inconvenience, and the pedal body separation issue which was a little bit tougher to crack but even less inconvenient, and those were first rollout pedals which I purchased in January of 2018. Both cost me zero downtime in terms of training. Hundreds of rides with issues on maybe 10 rides total.
Limited experience with the fully replaced pedals I just got (after 18 months of ownership), zero issues with BLE or ANT+ connectivity, or anything else so far.
