Works great, easy assembly and no issues!
Using the weedeater for edging was too hard, so I purchased this. It works great! It was easy to assemble and easy to use. My lines are perfect, but the size, durability, and power of this gem get the job done, and it's lightweight enough that I can easily maneuver it around the yard. I chose a corded one so I don't have to deal with battery life or charging.

Does the job without many frills.
Color: Sand, Size: Queen
Looks like it would be warm and cozy. Looks good on the bed and is a decent cover. I can't speak to durability and so forth, was recently purchased and used. The price was about what I paid for my own micro mink sherpa comforter and the ones I own are thick and fluffy and super warm. This isn't the same quality, had I paid more attention, I'd have bought one like mine in the tan. Seems fair though so let's see.

Red is bright red
Color: Red, Size: King
The quality of this is wonderful. It did have a funny smell, which I didn't care for. Four stars for the red one, as the red is brighter than in the picture. It reminded me of a Santa Claus suit. I gave it away. My friend loves it.
