I would buy it again with closed eyes!!! It defrosts and warms up breast milk in 5 minutes, cooks and grinds very well in 25 minutes. You need to cut the pieces small, but that doesn't take me much time. Basically, you throw everything in and forget about it. It has solved my hands. The only downside is in the warming up, where you basically don't have to adjust the time, you add water and when the water runs out, it stops on its own. Once you find the quantities it needs, it's very easy. It fits every bottle size. I have the tommee tippee, which is relatively bulky, and it fits perfectly. The spot where you add water gets salt deposits, but I boil vinegar for 1-2 minutes and it becomes new again. I don't know about durability because I haven't had it for long, but so far it's excellent!!!!
