very cost efficient, but not as comfit as the OEM one.
cost is way cheaper compare to the OEM one, brought those on sale which is less than $1 each. But i found the bristles will be much harder. and each group of Nylon Bristles is smaller as well.<br />not as comfortable as the OEM one also a little bit harder feel on the teeth.<br />they did refund me after email them the feedback. may worth trying in my opinion.<br />i would give only 2 star for the product, but added one more for the good customer service.
