I bought two of these back in May when Keywin first posted about it. Been running one ever since then on a X-Lyte 408 with bad hall sensors. Works just fine. I went ahead and replaced bad sensors in a second 408, so I'm not actually using the sencond one yet. Keeping it as a back up. Who knows how durable these will turn out to be. But, after using one for three months now, I would recommend it as an option for someone who doesn't want to replace bad motor sensors.
