I have a Frabil R2-tec, really like it. I don't have a lot of experience to compare to others, but it is very well built. Poles are large diameter & slide easily. It's Thermal
capability is great. No condensation, and i usually have to turn the Big Buddy off periodically because it just gets too warm in there.
Tub is thick and very sturdy w/ lots of room. Seats are comfy too. Only change that i would have had different is the slope of the front of the tub. could have had another seat there, but that slope doesn't allow it. But, nothing a 5 gal bucket can't solve.
It is a heavy unit over all, so keep that in mind if you are planning on pulling it, or loading/unloading from a truck bed.
Overall a great flip over for me and the kids.
