I've got all Vivosun stuff. The LED lights are fine. No complaints. I've had my tent (5'x5') setup for 5+ years now and the only thing I can say bad about it is that the front zipper is now malfunctioning. I had to rotate the entire tent 90 degrees so I could utilize one of the side flaps to get in and out. But, what can you expect after 5 years of zipping, unzipping, etc. Things wear out. Everything is going strong. The air filter motor's bearings are a little noisy on startup but they fall into place after about 10 minutes runtime. Again, something I consider to be a wear and tear issue. Not an inherent malfunction,
