High quality, good mechanics
Excellent quality
Delivery times as promised
Great replacement remote that is Nova compatible. Easy to program.
Excellent service and price
Since the Centurion D5 isn't supported at all anymore by Centurion Systems, I bought this scarce item as a "backup" for the day I need it. (Along with refurbished D5 CP80 controller, from another supplier though.)
Much easier to replace just the gate sensor & harness - or CP80 - than de-wire / re-wire all connections than replacing the entire D5 gate motor!
Arrive perfectly & securely wrapped and courier service was very quick.
Thank you!
The remote works perfectly fine
Excellent quality cup handle with a clean brushed satin nickel finish. It feels sturdy, was easy to install, and gives cabinets and drawers a modern, premium look. The 64mm size fit perfectly, and the finish looks great while helping to hide fingerprints. Very happy with the purchase and would definitely recommend it.
It is a great product.
Quick and easy to order keep it up
Great fans, they look fantastic and great for when you want to run quiet builds.

Fantastic service! Order arrived faster than expected
Good communication and good service
