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.
No. I haven’t cared as much about that and I’m not sure why. I’ve both learned the old fashioned way and haven’t minded the results. I very rarely get the internal temperature wrong enough to not enjoy the food.
