Product was defective from day on and lasted a whole 32 days and now will inflate but by the middle of the night you sleeping on the carpet.

The directions to put this together were unclear and failed to note that you need to use really oversized bags. After a few uses the sides have already broken. The clips are really hard to put on and off the the rack.

Published only a year after his masterpiece On The Road, Dharma Bums is a visionary look at the debilitating effects of fame and alcohol. It follows Ray Smith (Jack) and Jahy Rider (Gary Snyder) on a buddhist romp through the mountains of the west coast. Contemplating their religions and beliefs and coming to beautiful realisations about the world ("You can't fall off a mountain"), they create the rucksack revolution. A beautiful insight into thought and poetry. A must for anyone who wants to learn to think or expand their mind.
Positive
