I am using netgear modem from last 8 months .It is very good without occur a single problem. I was purchased it online.It is almost weight less. It support around 150 mbps speed and the range of the modem is very large. It does not heated.
I always open it day and night but it do not heat. It comes with 1 year warranty from company. previously I have beetel company modem .It had issue that at any time of working, it automatically restart but netgear has no problem at all. I use around 5 devices at the same time.
Many times it also fell down on the surface but it do not damage as well no problem in internal parts.The build quality of the modem is very good .In my opinion netgear is the best modem router as compared to any other.
