Feels amazing, but the colour is slightly lighter than pictured. When I checked the colour SKU it matched the colour I painted my office, however as stated, it’s actually quite lighter. Still an amazing product. 100% a manufacturer issue and not an issue from Deskhero.

Stripped screws and tightened beyond the limits

The keyboard case came pre-screwed in. Whoever did the **** job was apparently very mad because I cannot explain how overtightened the screws were. 2 of the screws were completely stripped and the rest almost stripped out just trying to get them out. I was under the impression that the whole thing would be disassembled but it wasn't and we cannot even assemble it because we cannot unscrew the case.

Fast delivery!

Great help

Thank you to jerrold for taking time with me to reorder my order that unfortunetly never arrived. Not their fault, i fully understand what happened. Great team

Package

I never recived my package and i dont know what to do. It says that it has been cancelled

Hi Justin,

Apologies for the delay - the tracking label got printed but never shipped it seems? or never picked up. We will pack a new Saka 68 green and provide you with a new tracking number.

Thank you and sorry again for the mixup

Great experience, great mouse

Decided I wanted to try the beast X if I could find a this model and straight up this was the only place I found one in stock. Usually if I’ve never heard of an online vendor AND they happen to have exactly 1 mouse in stock that I couldn’t find anywhere else on the internet, I’d think maaybe too good to be true. Glad I snagged it because the mouse is awesome and the Deskhero came through with a seamless purchase experience and incredibly fast shipping for free, plus the mouse and the TTC switches (was on the fence) are top quality

Shipping was extremely fast, and the product is excellent. I would highly recommend this seller.
