The product is great, definitely quieter and less drafty now. However, even after carefully measuring, both inserts are about 1/4 inch too short. Appreciated hiring racially and gender diverse staff in the warehouse. To be honest though, I couldn't recommend the service. It took months to place my order, then one window had a very noticeable flaw. I agreed to return it and pick up the replacement, yet Indow was not willing to take even a little off the cost, even though I'm saving them effort and money at my own inconvenience. I also got a pissy voicemail after not yet responding to an email that had been sent a few hours before. I know it's a pandemic, but still: not impressed.
