I am a 30 year consulting network and hardware person that has been involved with many many brands of network hardware over the years.  The last 15 years I have been installing Unifi hardware devices too small and medium size businesses and some residential.  I purchased some TPLlink hardware about 6 months ago and still very very curious of how it is ALMOST a twin to Unifi hardware?????  In the last few years I have seen alot of these hardware vendors that hit the small businesses and residential have literally have almost NO support, and hardly no documentation at all.  If you do not have much network experience..... you are going to have a long long road to figuring anything out. 

I have consulted 1000's of users all over the world who fight these types of struggles every day.  These types of hardware vendors are NOT PLUG and PLAY at all.  These vendors are offering very very cheap hardware now compared to Cisco, Juniper, etc.... and you get what you pay for.  Yes it is great that they are cheap, no licensing crap.......... BUT with Unifi you better carry spares on the shelf when they fail.... cause you only get 1 year warranty, bad RMA issues.... almost 0 support, no phone number to call and without great support ......any business's hardware is junk to me.  

I just got started with TPLink.....so lets see if they do much much better than their competitors..... if they do not then I will NOT be buying and selling their hardware anymore either.....

@Gabriellk I have played with a few, but I would consider them for a business where I am only dealing with may 10 or less clients, may push it to 20 if costs are a big point. Any more than that and I would go to the Unifi for my equipment.
