It is slightly softer than another wax I used before (Rex Black Diamond Hot Wax), which results in a quieter chain right from the beginning without a lot of break-in. I could mount it almost directly on the bike without having to move every single chain segment first. During the ride, I don't notice any significant change in friction compared to the previous wax. Although, this is expected and usually just detectable under lab conditions with precise measurements. So I just have to believe the Bike magazine tests.
The Wander Wax feels a bit sticky compared to my previous wax when touching the chain, so I recon that it could absorb more dust particles over time. When wiping down the chain with a microfiber cloth after each ride, I need a few revolutions until it doesn't leave any dark marks on the cloth, which i recon is all the dust accumulated during the ride. I will need to see if this has any significant long term effects on the chain, although the amount of set dust seems normal.
After around 400 km of road riding in dry conditions, I noticed the first dry sounding chain noises. So I re-waxed the chain. I had a similar experience with my previous wax - which is also usable for 800-1000 km - and stick roughly to a 400 km re-wax interval for safe measure.
