I started with Mr. Beer kits in their PET bottles and still have them in my closet. I use them as mini-growlers when I take beers. I bottle off my kegerator and those stay in the bottles less than a week. With proper care, I’ve never had any issues with mine and I’ve had them in rotation for almost 10 years. I used to bottle exclusively in them when I started.
Here is a Handy little link from @dmtaylo2 from a while back regarding getting the best out of your extract brews that I always found very informative and helpful.
