I have been using this mouse for about a year now and it is yet to let me down.
Before the purchase, I was sceptical about wireless mice because I had concerns over battery life, the extra weight (I had previously used one and found it uncomfortable) and wireless performance. I did not think I had much to gain by not having a wire.
However, after my old mouse became unusable and I was browsing for a new one, I found that all of the decent-quality mice were wireless. I found this one for a reasonable price and advertising 'invisible optic' technology, i.e. the optical element is invisible, increasing battery life. This claim is realistic, as a pair of Duracell batteries last several months even with heavy usage.
I also can't fault the wireless performance because it is more accurate than my last mouse, which had a wire. And, though I had doubted it, I did in fact benefit from not having a wire because it didn't get stuck behind the desk and restrict my movement.
In the first few days, the mouse did feel heavier than a wired one and it caused some slight pain, but I have since got used to using it and it no longer presents a problem. I can recommend this product.
Whilst the LX7 promises to combine everything needed for the average multimedia man (someone who enjoys viewing films, editing pictures etc), I soon found this device a small disappointment. After hearing that it had an internal zoom feature, I was quick to buy one and try it out for myself. What I didn't know was that, although it does work, it fails to zoom to a large enough capacity in order for me to find it beneficial. If, like me, you want to be kept assured that the product your buying will outlast all others and provide a lifetime of use and committment, then this is not the buy for you. In terms of it's mouse use...well it's your average wireless mouse that works well and allows smooth glide over the screen unless the battery is weakening. Speaking of the battery, it can, an I emphasise CAN last up to several months, but it can be a challenge to switch it off on the seperate button on the side. By doing this, you can save energy and make your average lithium batteries last a long time (around 4 months).
