You sure your Pc's USB slot that you used isn't damaged? I have a similar problem at work with a USB slot when trying to charge my phone it will pick it up but keep losing connection.
As for another mouse there are many options I was just trying to help you out since a new mouse would probably now give the same problems and you had a fluke, I would've returned it the next day if that happened to me
Some options:
Logitech G500-700 and also the GX9
CM Storm or Storm
Roccat Koni XTD
Steelseries Sensei is like the deathadder which you don't like the majority's favourate so perhaps you will like it, pehaps you won't since you don't like the deathadder
Another SS mouse allot of people these days neglect is the XAI which is also good imho, also the Kana V2 which will make it's release in the western world soon looks promising...
Thermaltake Tt eSports also have some nice ones have a look at the Black Element, the Black Element Cyclone and the Theron Infrared if you want a more basic mouse...
I will not mention Razer due to your personal preference
In my honest opinion I tend to buy a mouse for comfort not the amount of buttons ect. Those are all extra,
