Query: Smells bad hard to keep in one piece

hard to get air inside the tent also was scared i might suffocate =( i might try to get a refund or return this but was really hoping it would work better to reduce light around my bed. the hole in the top is small and doesnt work well either and lets in light and there is no other real ventilation on corners etc.
