> It also doesn't contain any nasty chemicals, unlike several of the powders

At least in the US my experience has been the reverse of that. Several of the companies seem to have used the pods as an excuse to increase the number of chemicals that require chemical burn labels on the packaging and switch "Best By" dates to very literal "Use By" dates. With those pods, there's a thin water-soluble plastic that is also prone to melting at the posted expiration dates as all that is between you and second or third degree chemical burns.

No thanks. I worked food service in High School and had more than enough Chemistry classes in college to have too much healthy respect for chemical burn notices to trust any of the pods at this point. (Especially as someone who lives alone and will almost never use an entire package of pods before "Use By" dates.)

I haven't tried powders, but I did go back to liquid detergents even though there's only about one option left on store shelves where I shop which have now devoted so much space to the wasteful plastic tubs of the pods.
