Summary: after 5 years of use, it has started giving problems and goes unresponsive. Now that its dying, and i surfed the market for replacement, and it turns out that this was the best mouse in its price range. Excellent for gaming, very responsive. I would love to get hold of it again.
Summary: I like this mouse. It has a good ergonomic design and customisable buttons, along with up to 2000dpi which I find is enough. Solid mouse and my last one from 2011 is still working fully, I decided to buy a new one as I don't think they are widely available anymore. I know people talk about the side buttons being too small, but in fact it just takes practice. Fully recommend.
Summary: This is a really good mouse. The symmetry is quite useful as I use it for both left and right mousing, depending on my mood. The switchable DPI settings are actually quite useful (sniping in games etc). It's comfortable enough to use for long periods, could be a little heavier though.
Summary: Bought this mouse to replace a failing Microsoft Laser Mouse 6000 (sadly not in production any more). It has a very nice feel it, slides effortlessly on the desk, very good precision and good size. The one complain I have it that the side buttons are recessed which makes them very difficult to use. This didn't really come as a surprise, it is clearly stated in the description and is in fact a design feature, albeit a poor one IMHO.
Summary: I really like this mouse over my previous mouse which was a Microsoft intellimouse explorer version 1. The dpi settings are very nice and it slides on my desk effortlessly. I can see why people are complaining about the size as the buttons are small and are quite far up the mouse. I would not recommend this to anybody who has small hands as I myself can only just about press the side buttons. But overall a great mouse.
Summary: Excellent product, very responsive and perfect for gaming. I'm using 800dpi setting, I find that this is the best for all round use. Esp gaming. The side buttons are a bit too far forward, but I think I'l soon get used to them. Just a design flaw. I think whoever designed this obviously wasn't a gamer. All in all tho, a good product at a good price. I would recommend it.
Summary: This mouse is fluid and doesn't require a pad for just general use. As far as gaming goes a pad is a necessity and this mouse is a good budget option. It has a good shape so it fits into your hand well. The only things that aren't great are the mouse wheel that is quite cheap and the side buttons that are out of reach when you hold the mouse normally.
