I did not actually purchase this item my sister passed it over after using it for her 2 children. I can tell by the sticker on the box that she paid £15 and it came with 4 bottles and a bottle and teat brush. This was approximately 9 years ago and would be a very good price today! I can't really say whether I would of brought this exact one as I did not look at any in the shops but I did know I definitely wanted a microwave steriliser.

The unit comprises of a white plastic base that has a light blue coloured plastic insert that has several holes in it and a raised plastic point in the middle to lift it in and out. The lid is a semi clear plastic that has a handle on the top and clips on via 2 clips at the sides of the white base. It is incredibly easy to assemble and disassemble and extremely strong and durable. It is doing well after our years use as well as doing my sisters 2 children and will be perfectly fine to do more babies that we will hopefully have.

To use the steriliser you pour 200ml into the white base. There is a handy sticker on the lid to remind you how much, but the lip in the well of the base once the water reaches the top of it is exactly 200ml so you don't even have to properly measure. Do not forget to put the water in as you will damage the unit and possibly the contents if you forget. Then put the blue insert in the base with the items you want sterilised. The blue insert has small plastic flat arms that you can push up to 4 Philips bottle on to and place the collars and teats around the bottles. Then put on the lid making sure it clicks both sides then place in the microwave for 5 minutes.

Once the microwave has pinged wait another 2 minutes before opening the steamer. There is a sticker on the lid that says if you do not open the lid the contents will stay sterile for 3 hours. Another sticker on the lid also states not to put bottle and teat brushes in the steriliser. If like mine your microwave is on a higher shelf be careful when taking out as it is very hot and some water moisture may get on your hands that occasionally I find to hot to handle it without oven gloves. The same goes for taking the lid off, all the water moisture in the lid may run on your kitchen side unless when you take the lid off you angle it so the water runs back into the steamer.

I have a Philips Isis breast pump and the parts fit in with a bottle for sterilising as does other bottle makes like Tommee Tippee it's just that these bottles do not fit on the arms.

I have found this piece of baby equipment very easy to use, strong, durable and would happily recommend.
You can buy in all most baby shops and supermarkets for approximately £20 to £30.
