5 Excellent value for moneyCovertLoneWolf | 23/09/2011 | See all CovertLoneWolf's reviews (2)This mouse is very well built (I have already accidentally knocked it onto a hard floor from about 4 feet and it is fine), it is precise, responsive and lag free. I use my computer for gaming and have found it more than upto the job for this, which considering the price is saying alot. I don't find it quite as comfortable to hold as my old mouse but that is more down to personal preference than anything (I had been using the same mouse for about 6 years so my hand had pretty much moulded to it). I can't really say if the battery life will last as long as claimed as I've only owned it for about 3 months, but I am a fairly heavy user and the batteries are still going strong. All considered I don't think you are going to get a better constructed or performing mouse for the same price, and would highly recommend it.
