yep - mine improved my balance so much it was well worth it - i didn't realise just how much it would help till i spent about 4 weeks on it regularly and then went surfing... it was incredible, I stayed on my board for so much longer and didn't wobble as much. a miracle!
like dbbb said, they're great fun too. you can watch telly or chat on the phone at the same time!
can't use mine at the moment though
* edit * wrong name sorry! I'm not seeing straight due to strong doses of oral morphine so i have an excuse - soz essex! you could have said that though!
