I love the 4 season solarium! Two men (not professionals) put it together in about 8 hours with very little difficulty. I'm a little concerned about the windows holding up to the winter winds but we'll see. I bought it to provide a comfortable place to sit outside and to keep the bees and the flies out of my food when I eat outside. It has more than met my expectations in that respect! However, it doesn't keep out the mosquitoes. I would definitely recommend this product because I don't think you will find anything better than this - I sit out there to relax every day.
