For me, it's a bidet toilet seat. I bought one that didn't really fit as well as I hoped, so now I am shopping for a v2 based on experience. I don't want to live without one going forward. That's for sure.
I read a lot. I used to always keep a paperback book with me ever since I was a teenager. My Kindle goes everywhere with me, since I got my first one in 2009. I just wish they’d make them smaller, the first Oasis was the perfect size for carrying around all the time (I’m a guy, no purse).
