I got this in the box, brand new. It looked alright. But when I got closer to it, and started inspecting it. I threw it on the lathe with 3 micrometer dials and it's completely twisted, bent, and not straight. Not only were the 2 circle halves bent and angled inwards slightly, the actual shaft was slightly twisted. In order to fix it, I had to re-balance the crank by lathing fractions of mm off and hammering it back to true. It was off my 2000th', which is actually ALOT when spinning at high rpm, but is not true to 40,000th mm. I would not reccomend this crank or any of the other Doppler stuff actually. I bought several high dollar Doppler parts thinking they were going to good, but the quality is just not there.
