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.

Ex Output:
positive

I bought this to test it out since I needed to buy several solar lights. The detachable solar panel was a huge plus. I left this out sitting along with another unit from a separate company for a few months I got busy/forgot these were out there. Well I went out today to install it and this unit is dead. I popped the battery compartment no seal in the lid. one of the batteries corroded. So Im going to see if I can bring it back to life with a little cleaning. for now 1 star because it died after a few months of rain.

Ex Output:
negative


Ex Input:
It was great at first. However after about three months, I notice the performance was becoming poorer by the day. The water pressure is good for about one week with new batteries then very weak. I tried different types of batteries, always same outcome. So I bought rechargeable batteries to use. But after another 10 months, the waterpick stopped working all together.

Ex Output:

negative
