I buy from Best Buy with these kinds of products. I use my mouse for both work and play. I go through a mouse every 2 years or so. Their warranty for $15 is pretty much no questions asked if there's any defect at all and within 2 years you can either get the same one (and razer will usually still sell this for the next 5-10 years anyways) OR store credit for me to use this $60 for another mouse with warranty again. So I'll get at least 4 years of use from one payment of pretty much 120-125% of the cost of the product, and that is even if the product lasts 2 years. Pair this with some best buy gift cards with 5-10% off and that might bring it down to $5 for that warranty. I always have problems with these razer mouse at around the 1.5 year mark or so.

FYI: The warranty is roughly about 30% of the cost of the product.

Just a heads up, micro USB.

It might be an unpopular opinion, but replaceable batteries are superior to built in batteries in most things. In a mouse like this a single rechargable AA lasts months, and can be changed in seconds.

Having built in batteries that are guaranteed to go bad and render the whole device landfill at some point feels like planned obsolescence.
