Described as not only the highest performing AP available, but also the best value. UAP-AC-HD is the top model in the UniFi range & comes fully equipped to handle pretty much anything that gets thrown at it. Capacity for up to 500 clients spread out over a massive 120m range - oh look, instead of me typing all this, it's all here on the UniFi site, go read it.

It does stuff like this:

Surplus to requirements, purchased for an ambitious project that didn't proceed, it's unopened, new in the box. 

Pricespy has PB with the lowest retail price - $605 & I realise that this is not going to be a profitable investment. If you're interested in owning what's probably the world's best WiFi AP, then hit me up with a reasonable offer. By reasonable, I mean north of half price.
