I was very pleased with the steel washing up bowl, doesnt seem to flex when lifting it when full to water the plants with. A shame the squirt bottle has a plastic spray nozzle, but at least it is reusuable.
Perfect for out & about when I don't want to lug my copper flask with me (or have to drink from a plastic bottle!). Lightweight & sturdy, it actually holds slightly more than the 500mls which is even better. The carrying handle is great too. 10/10 for quality. An excellent buy.
These are great, totally leakproof for on-the-go, but also very happy to sit in the fridge!
