However, I found that that the Rival 500's generous controls may also contribute to its biggest problem: a lack of weight. As with other mice with 10+ buttons, there's just not much heft to the body of the mouse itself. With no option to add more weights, the mouse feels feather-light, and not in a good way. This isn't a huge issue, especially if you like lightweight mice, but it's the cost of essentially having a keyboard in your right hand.
Dell Home, via its Member Purchase Program, offers its Dell 15.6" Laptop Gaming Backpack in Black/Red for $28.49 with free shipping. That's tied with our expired mention from four days ago as the lowest price we've seen for this bag. (It's the best deal we could find now by $20.) It accommodates laptops with up to 15.6" screens and features a shock-absorbent EVA molded front shield, adjustable shoulder straps, and a deployable rain cover.
