What features are your concern and maybe I, or another member, could help? They are great tents. We own a T4 & T4+ and our camping friends have the T4+ & T3. We've used them camping on an island in heavy storms (40+mph winds with 18mph sustained for 3+ days) and had no issues. I can't speak highly enough about them. Also, worth noting, the customer service is beyond top notch.
My concerns are from what I have seen on You Tube or read in forums, things like, The floor is removable because it easily gets holes in it, The corners where the floor attaches are not velcro'ed shut, thus snakes \ insects could get inside the tent. Attachment points on the corners where the tent stakes go easily rip off.
The floor is removable for ease of cleaning. We find this extremely useful after beach camping. In the case you do get a hole in the floor,, as we've all experienced with a tent,, it is comforting knowing you can buy a new floor on the website and your nice tent isn't trash now. Gazelle offers multiple replacement parts for all their tents. These can be found on the webpage under each tent.
The corners are velcro where screen porch poles go on the T4+ corners. Although it isn't a 100% sealed area, due to the poles, it easily mashes around it with the pinch of your fingers. The others do not have poles, being a pod system, so this isn't an issue.
The attachment points on ours were used in the storm I mentioned in earlier post. I tied one guy wire to a shovel and buried it off the right side. Even with it being taught and 30+ mph winds, there are no signs of tearing. Neither of the other 2 Gazelles, another t4+ and t3, suffered any damage either.
One thing to keep in mind with online reviews that seem mainly negative is the user behind it. Sometimes ignorance leads to mishaps and not the product. I respect your side of caution, I am the same way, but know that Gazelle makes a wonderful tent. I don't believe Michael would put his company name behind a product that wasn't top notch.
I hope this helps in some way.
