Best/cheapest wheels

I have officially fallen out with Savic 12" wheels

I had three hours sleep last night (which is bad for even me), because my pair have started to sqeak sooooooo loudly!! I've had to dish out paracetamol's in abundance to Cheiku and Floe today cos they've given themselves headaches from having a gentle sprint.
Not to mention they've started to tilt because the plastic's worn away!!

Really annoyed.

Can anyone suggest a longer lasting, cheaper, quieter alternative that's isn't a flying saucer?
Links would be good

i use a silent spinner, not sure if it comes under ths same banner but looks slightly different to that one in P@H. hope it helps!

i had the same problem with the savic and when i got a new one they refused to use it!!!!

i got 2 silent spinners problem is they are not all that silent and not cheap either at about £25 a go!

I haven't had any problems with the silent spinners, I still find them quiet and some of them are around 9 months old I had mine of ebay I found them for £13.87 and £5 for postage, but that was a one off cost so if you had 1 or 10 wheels the postage remained the same

yeah I concur with Brandygirl

SAvics are a pain when they wear - I quite like them as wheels so its a shame!! Whatever you do dont buy a 'comfort wheel' OMG they are horrific noise wise!!!
