Great choice

For clarity, there is no tape nor is assembly required. I only gave 1 star for each since neither applies. In the past I have purchased another brand. I was pleasantly surprised to find this was wider than the other brand - which, allows for better weather proofing. Very durable, easy to use, cuts easily with regular scissors. Blocks a lot if hot air from entering.

Good product

The foam around my a.c. Stopped the draft immediately and the cover worked great to protect my unit and seal the window from the cold weather in Northeast WI. I've never left my unit in the window and this product secured it well from winter's bite.
