This is finally a very good news. Instead of the expensive original I once tried out this. Very good cleaning result, super-fit, super smooth teeth, can be put on easily and pull. Durability I have to check. Bristles shine a little more. Are delivered without caps, but the originals cap fits it. Should not be surprised if they are produced in the same plant me. Unfortunately keep our elec. Philips Toothbrushes handpieces (always battery defective) max.bis the expiration of the warranty, buy again and again then a new handpiece, since no alternative is on the market that looks so good. If this time a good substitute reconstructs I'm doing immediately. This Ersatzzahnbürsten I buy again, this is a good choice and they cost less 4X.
