I will agree with what a number of other reviewers have said in that they are rather expensive for a simple accessory item. They seem to be well made, but basically they consist of 8 lengths of aluminum tubing, some web straps and a few simple connecting pieces. For that I paid $95, but if you're willing to pay, the product seems to work as described.
I don't intend to bring them with me on trips, but they are so light it wouldn't be a hard decision to pack them. I got the higher 31" horses and it actually seems higher than that when I used it. Imagine it's the height of your typical ironing board. Great ergonomically if you're working on your boat.
These are not for the thrify minded that prefer the 2x4 look to everything, but if you appreciate quality lightweight gear these are worth a look.
