★★★★★
Beautiful finish and construction. Better than any residential diffuser I have ever seen in all my 30+ years in construction.

I spent way too many hours during our renovation looking for vent covers with a more modern look — not the simple ones at Home Depot. These look modern and sleek. Customer service was extremely helpful via email when I had questions about which ones to order. Highly recommend.

In three weeks, these replaced the cheap contractor-grade registers that were rusting in place. My wife commented she was no longer blasted with air in bed — the distribution is so much better throughout the whole house. The aluminum construction and ease of adjustment mean they’ll be here for the life of the house.

We have purchased and installed more than 60 grilles from this company and everything we have received has been in top quality shape with straightforward installation. We also use these on several projects at our church and school facility — we love the ability to custom size them, and they hold up very well in classroom applications.

One of eight covers wouldn’t fit due to a shared wall situation. The company understood my circumstances and custom made a replacement unit for me at no charge — and it worked perfectly. That’s what I call great customer service.
