Review on Polish-Friendly Flexi-Attachment Extension for Enhanced Compatibility by Jay Maryland

I hadn't realized it didn't come with the driver cover that comes with the Dremel, I just assumed it came with it. Useless to me until I buy someone else's driver cover. I can't say how well it works yet! Checking review on 10/23/20 because I went ahead and bought a Dremel driver cover. The product still does not work because the square end of the inner flexible shaft is too small and rotates inside the drive cover. As a result, the cartridge does not work. I then replaced the inner shaft with a shaft made for a Dremel flex shaft and now it works. OK. I do not recommend this product. You're better off just buying a flex shaft from a reputable brand that also has the best shaft lock.
