Stink I could not find has proven super .... Personally for me a recommendation ... and the price is absolutely fine with me. To what extent other products that are more expensive are better I can not judge. So until the sudden tearing of the rubber after less than two months (something goes not) It's dangerous ... for the sensor ... the the front part is simply pulled out, you can the part even after two months not return real scrap, but I ordered the bellows again, maybe it was a one-time error, until then 1 star less unfortunately is not. Will report the second bellows proven how.
Supplement got a new Bellows immediately after a complaint ... the now works even after several uses.
