OObrush Refill Brushes x2 (Medium)

Love this weird toothbrush, feels good once you get used to using it but these brush do seem to deteriote quite quickly (maybe a couple of months) but at the price that really isn't a big deal. I gave 4/5 because I'm yet to return to the dentist/hygienist to see if they notice any difference. If they do then I'll be back to up it to a 5 but at the moment I reckon they might be marginally better - but I'm no expert.
