I have requested a waterpik for my birthday but I don't really know a great deal about them; what is a good brand, make or model, what's the best sort to buy and which ones should I avoid? I would prefer something portable for when I'm staying at my boyfriends house or away on holiday, business etc but I don't know if a portable version reduces the effectiveness because it's portable? Me and my mum had a quick look last night and we found some for £50 and some at £150!? And if I use a waterpik does this mean I can stop battling (and loosing) with Superfloss?
If anybody has any advice or recommendations I would be very grateful to hear it.
