I like my SpringBar Leisure Port Synthetic; I don't love it. The structure of the tent itself is top notch. I've had it up for over a week in several Florida thunder storms. No problem handling 20+mph wind with gusts and heavy downpours.
I have some minor gripes about the shelter. The tie straps are annoying and not sewn or fused at the ends. The screens in it are somewhat useless. There are large holes at the top (4x 4in2) and bottom (1-2" around entire perimeter) for insects to pass through. The poles are stupidly heavy steel (31 lbs). I dumped some rusty water out of the galvanized steel poles after 7 days outside. The vinyl floor is well built, but faded noticeably where exposed to the sun in 7 days. The lower fold on the fabric panels seems to collect water and hold it. After two days without rain water was dripping out when I removed them. I'm still waiting on a resolution to that.
I contacted SpringBar about it and was not able to describe it well enough to be understood. And found this is the first run of the Leisure Port in 25 years.
Overall, the design lends itself to breathable canvas more than urethane coated polyester. It is usable, but will require significant care and drying time (more than canvas) to avoid mold. I'm afraid to store it in a bag or bin. I'm not put off by SpringBar, but I will not buy another synthetic or with steel poles. I don't need help to set it up, but I do need help to carry it.
