Very good product - recommended without reservation.
Really simple to use. Day after receipt, steamed salmon in the bottom level with two different veggies on each of the other layers and at the end of the cooking time the results were really wonderful - and reminded me of how vegetables ought to taste but too often don't!
Since then used for more dinners than not, although not got round to trying other main components (chicken or whatever) apart from the salmon, or (new) potatoes either yet.. But success with all the veggies tried thus far - carrots, mange tout, French beans, sugar snaps, sweetheart cabbage, cauliflower and calabrese, all crisp and tasty.
The instruction leaflet is a model of how these things should be too - written by someone for whom English is a first language and well thought out.
Would heartily recommend.
