Logitech G203 double click problem

[Things change I've changed]

Hi, I have a Logitech G203 mouse that is just under 3 years old and the left mouse button and also side back button have double click issues, it has been driving me nuts, I've never had this problem on a mouse before, is this because it's a budget mouse?

I'm guessing there is no easy way to fix this, I'm thinking of grabbing the Steelseries Rivil 3 but worried the same thing might happen again, is worth me upping my budget a bit?

I noticed you can get the Razer DeathAdder (Essential) for only £27, is that a step up over the G203 and Steelseries Rivil 3 in terms of quality?

Right, apparently the G203 and Razer DeathAdder is only rated for 10 million clicks, the Steelseries Rivil 3 is rated at 60 million! So I think I might give the Rivil 3 a go.
