I use 2 tubes tied together and my 5 yr old daughter has no problem with it, can definitely tell when she stops pedalling!!

I had one until it did a great job protecting my head in an endo to rock crash.  No concussion or injury, just a cracked helmet.  Loved how light it was and fit my fat head well.  

Need to keep an eye on the screws that hold the chin bar latches on.  I lost both, but was easy to fix with a cotter pin.

These are shipped from Canada.

A buddy and I split a set to use on the rear only.  Most reviews complained that u can hear the insert rattle a little bit when at low pressure.  I have found that to be the case if I don't check the pressure before I ride and it is at 22 or lower.  But I am 220lbs fully geared up and I usually run 26 or so in the rear and I cant hear them rattling.. I ride fromme mostly and smash stuff pretty hard on a 29er reign, haven't gotten a dent or loose spoke since November, riding at least twice a week.

Immonator, can do quick laps, has most types of features.
