My £40 R&G grips have 5 settings I adjust - I've never really thought - 'Blimey, wish I'd spent 100 quid more so they adjusted by themselves' - but perhaps its like sliced bread - somebody had to start producing it till we realised how handy it was
I got the Oxford Heated Sports Grips and I am quiet happy with it. A friend of mine got the CLS on his Triumpf Speed Triple R.
