The best!
I’ve had about four of these now and this one is by far the best yet! First of all, it’s ultra durable. Secondly, it’s actually large enough to be considered an extra-large for large dogs! I haven’t had any issues with cold drafts or excess heat loss. The magnetic closure works very well. I can tell that this one is going to last much longer than my other ones did Finally, a really truly great quality dog door! Thank you! I highly recommend this one!?? Gibson
