As the priciest mouse currently on the market and the flagship model for Logitech's G series, the G7 has some hefty expectations to live up to. For this price we were really expecting something special and amazingly, Logitech has managed to outdo themselves once again. This is everything we could want from a mouse, and whilst you pay through the nose to get it, for those seeking peripheral bliss the G7 will be just the ticket.

It carries the now flagship design that has been used by Logitech over the last few years. Completely inaccessible to left handers, it is smooth, curvaceous and incredibly comfortable slotting perfectly into your grip. There are grooves running down either side that accommodate the thumb and finger, and the seamless, polished finish feels great. We happily gamed away hours and hours without a hint of soreness or cramping.

Keep in mind this mouse is firmly targeted at those reclusive few who need the most out of their games. It performs superlatively in all desktop tasks, don't get us wrong, but to shell out this kind of money you really need to have a specific purpose in mind. Gamers will be treated to a brilliantly precise, robust mouse that is simply put, the best performing solution currently available.

Using the same 2000 DPI sensor as its wired brother, the G5, the G7 is flawless in terms of accuracy. Never again will gamers be able to lay the blame at the feet of an underperforming peripheral (we've all done it).

It also utilises the on-the-fly sensor adjustment that made the G5 so popular. The G7 has three sensitivity settings which can be customised in accompanying software, and these can be jumped between mid-game with two buttons resting under the scroll wheel. This allows for you to have different settings for different situations which is a fantastic convenience.

What the G7 is missing compared to its counterpart is the adjustable weight option. The G5 had a cartridge that could be loaded or unloaded with tiny shells that changed the weight of the mouse. It was a very nifty function and will be missed on the G7, but it's not a deal breaker by any means.

What you gain in place of this is wireless connectivity. The weight slot had to be removed to accommodate a battery pack, and the G7 comes with two so you'll never run out of juice again. We love the way the charging has been implemented. The package comes with a tiny, USB-key sized receiver, which is all you need to get your mouse up and running. However you are also given a USB powered charging dock which sports a second USB port of its own. You plug this dock into the USB Port, plug the receiver into the dock, and you have a completely wireless mouse and battery charger which takes up barely any space at all. No more plugging in the mouse to charge, or running out the door to grab some more AA batteries, the G7 has power all the time. This is the kind of implementation we've been waiting for to make a truly viable wireless mouse.

The wireless technology is flawlessly implemented too. Gaming addicts often lament the woes of wireless mice when it comes to pinpoint precision, but the G7 overcomes this resoundingly. It is the first wireless mouse we've felt truly competes with wired mice of the same level. If you can get your hands on a G5 and G7 in a store, test them against each other and you'll find very little if any difference between the two.

We did have one very tiny criticism of this mouse; like the G5 it has only a single internet button. Normally gamers will rebind these to assist their play, and having only a single button is a bit of a downer but keep in mind the scroll wheel acts as three additional buttons so most people should be more than adequately catered for.
