I've been looking at LanShan tents, are they recommended?

I saw someone on r/Ultralight post their gear setup and they are rocking a 3F UL Gear Lanshan 1 Plus tent. So I started looking into the LanShan tents and came across This One but I also found This one on Amazon. I am not sure if they are the same tents. I currently have a REI 2 person tent that is too bulky and heavier than I would like for backpacking. Should I go for the LanShan? Pro or non pro version?

I also saw on the 3fulgear site that the tents are unsealed and needs seam seal by silicone glue?
