I took a little gamble on this product to be honest but it turned out to be great. This is an awesome product, even the nest engineer who came to fit it was impressed :). Attention to details and craftmenship is commendable. This is 1000 times better than the white plastic cover supplied by Nest. I would highly recommend this product.
I was worried that this might just be a plate someone had cut in their garage to sell to people who spend near £200 on a thermostat. Luckily I was wrong and it's actually a lot nicer than I expected. It comes in a nice box to start with which meant to me that they probably actually care about the quality of the product and secondly it's been manufactured well too. For the £18 I paid it's not cheap but then I wouldn't really say it's crazy expensive either. It looks a lot better than the plastic back plate so I'm really happy.
It's a bit annoying that the Nest comes with a wall plate that does nothing to complement the thermostat's modern design. The Elago Aluminum Wall Plate is a simple design that does the job that the supplied white wall plate fails to do. It is easy to fix and the perfect size and although it isn't cheap it does the job.
