I am pleased with the 31" Talic Seahorse stands I recently received. While I don't use them for storing a kayak, I find them very useful for cleaning or doing other work on my kayaks. It is much easier to do with the boat at waist height. They readily hold kayaks of varying size. They are lightweight and collapse to a small easy-to-store bundle that could be carried in a boat.
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.
This is a product that I've been very happy with. While the higher cost of $78.95 may be a downside, the upside is that you get a very high quality product. The construction is superb and it's easy to use. Opening and closing, as well as storing, is a breeze. The saddles cradle the kayak gently, and even when I'm doing a lot of work on it, it holds the kayak firmly. I washed my boat today and waxed it while these horses firmly held it up. I also use them for storage, so that my kayak doesn't have to sit on the ground in the garage.
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 excellent stands. Very light, very compact, and very nicely designed and made. Self opening which really helps set-up and when moving them around. Good on hard or soft, level or uneven ground. The taller ones put the boat at a great height to work on it. These could easily be put in a hatch and take up very little room. Might not need stands for tripping - but would help keep the critters out and make field repairs on the boat a snap. Would not be hard to think of other uses...
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.
