Q: Do not replace your Bose headphones. Get these replacement pieces, throw the stock ones away. These will make your headphones sound the way you hoped they’d sound when you got them. I went for a 20 mile bike ride with them stock and when I got home I checked the mail. My replacement (nibs?) were delivered. I put the new ones on and threw out the old ones. The sound is incredible. Get them. Even if you aren’t sick of the stock nibs. Get these. You won’t be sorry.

A: positive

Q: The reason that I purchase this mosquito killer is that it is non chemical killer. It is very safe,convenient and clean. And the night glow is very soft. It is just like a night light. Works very well, We just put it on one day ago, there are a few bugs already. I love it. No worries this summer.

positive
