I had the first Gen one, which I believe all leaked, and got a new one on warranty.
We had two of these newer gen ones.
My guide was using one this season and had issues with water coming through the floor, then poles collapsed under high wind. I still have a 3 season one and have not broke it yet. been in a little bit of weather but noting bad yet.
We have since replaced the broken one with the 4 season model but yet to test it.
Have seen alot of the MSR hubba hubbas do the same thing under high wind.
Both are a very similar design, light and easy set up. not super durable and will not handle high winds(especially cross winds).
Pros are: very easy set up,good space, ventilation is pretty good. Double vestibules is great as is double doors and great weight.
Cons: thin floor would be easy to rip, does not handle high winds, single zips on doors is a bit annoying on the newer models.
for tents you have cheap,light,strong. you can only choose two.....
All depends on your usage.
