The budget sterilisers work perfectly of course. They dont come with any bottles or teats. They are non-branded. But they are large enough to fit whatever bottles and teat system you have, plus they can also fit whatever breast pump you have.
Add water, put in microwave, and hey presto all your baby feeding gear will be sterile. Keep the lid on and the contents stay sterile for 3 hours.
You can order these online. Its nice to be able to offer an affordable option of steriliser!
