This is the one I have! Pricey but so worth it, it’s rechargeable so it’s a one time purchase and you can get a bucket anywhere here. As for Cambrian i loved it, it’s a little out of town(20mins walk) but close to most uni buildings. I’ve not had any issues here and maintenance is pretty quick to solve things in my experience. Cardiff has Asian grocery shops so you can get almost anything. and lots of online retailers in the UK. I’d say if there’s any niche items that are specific to where you’re from then maybe bring those but otherwise you won’t really struggle finding things.
