I have no hesitation in recommending the company or the product to anyone
The item I purchased (I remote PIR for an away-from-the-home garage) arrived as expected. However, there was a fault (unusually) in that the PIR could not 'learn' the remote. I called, and on advice returned the item.
It turns out that the remote had a fault which was not detectable. However, the customer service I received, the advice given, and the fact that a replacement was in my hands within two days is faultless.
I have no hesitation in recommending the company or the product to anyone with similar requirements
