Query: Do Not Waste Your Money

I thought this, being an upper end product would be great. I returned my first one after a week thinking that there was just a problem with it, but my second one reacts the same way.I constantly have to hit the connect button on the bottom, or my keyboard quits typing all together. Most of the time even when connected, it misses letters and doesn't keep up. I am so frustrated with this product that I took the time to come on here an write a review - something I typically don't do. If I can save one person the frustration that I am going through, it will be worth it.Oh, and I gave the product a star because I do like the mouse.
