My favourite and go to peripheral brand!
This is only my personal opinion - I avoid their laptops due to the price and the fact you are able to get the same specifications with other brands for half, if not less, of the price of their laptops.
However, every other Razer product really does shoot competitors out of the water. I have had their Earphones, the V1 and the V2, their headsets (Kraken), their mice (currently using Deathadder V2) and the list goes on.
Their mice are out of this world - you will not find an alternative!
Although their prices are more expensive than competitors, you get what you pay for. The standard of their products is incredible and you will not find the same with other retailers.
I have had an issue, a few years ago, with the earphones. They sent out a replacement almost instantly and had no hassle whatsoever!
I have not had any problems with any of my Razer products since and have not been required to request a refund or replacement.
I highly recommend Razer, their products, customer service and even their delivery (excluding the current global pandemic) is great!
