I bought my daughter the Fridge Phonics set for her 2nd Brithday and have been really pleased with it.
The set comprises of 26 magnetic letters, all of which are about 5 cm wide, 4cm high and 2 1/2 cm deep. They are nice and chunky, so easy for little hands to get a grip on.
The main unit takes 2 AA batteries and also attaches to your fridge magnetically. There is a switch on the front of the main phonics unit which allows you to turn it on and off and hs 2 volume settings. There is also a button which when pressed sings the alphabet song.
Each of the letters can fit into the main phonics unit. When pressed in the unit says the letter name and sings a short phonic song relating to that letter.
I have a silver coloured fridge and found that the letters scratch the surface when my daughter slides them around, so they are now banned from the front and have to be used on the side of the fridge.
My daughter has learned a lot from this set and we often use the letters on their own just to make up words on the fridge.
The letters are a good size, so not a choking hazard and would be very difficult for a child to swallow.
I often see this toy on offer for less than £10. I was lucky enough to get it for £4 at which it was an absolute steal. Even at the standard price however, I would say it's well worth the money as it's very educational.
