I bought this because I was looking for a steamer with plastic-covered (ie insulated) handles, and this is one of the few options currently available (I used to have a really good Sabichi model but that has been discontinued).
Although it lookss good, and the handles don't get too hot, overall I'm quite disappointed. The base pan is quite small, with a rounded bottom, and the steamer unit sits quite low into the base unit. This cuts the capacity of the base down to no more than 1.5L, not very good if you want to cook, say, potatoes in the base while the other veg steams above. Also the rounded base means I can only use my smallest gas ring and then only on low, else the flames lap up the side of the pan - I think I'll have to boil the water in my kettle first else it will take an age to heat up in the pan.
Another minor issue is that there is no steam vent in the glass lid, so eventually steam starts to come out of the gaps between the pans.
I'd only recommend this if you are looking specifically for a steamer with insulated handles and/or you are only going to be cooking for one or two people.
