Summary: I have to say I disagree with the other reviews. This mouse is the greatest. I can't find another full-sized BT Mouse anywhere. And, with my big hands, I love the size compared to other BT mice. I would actually prefer it a bit larger still, but, hey... it's definitely much larger than any other BT mouse I've seen. I use the BT600 with a PC running Windows 7, and I've had no responsiveness or connectivity issues (until recently...I'll explain in a minute).
Summary: The BT600 mouse is very well made, feels solid, and has a great rubberized surface that makes for easy handling. Unfortunately, I don't think its fair to call this a full-sized mouse. This mouse is smaller than almost every "standard" mouse I've ever used, including back in the early 90s when mice were pretty uniform in size, and generally smaller than desktop mice found today. Now, I've got long hands, and that makes it an issue for me (I returned the product).
Summary: I have had connection issues with this mouse and was ready to write a negative review. Before doing so I looked at the comments associated with the other reviewer and noticed that the manufacturer had entered a comment suggesting a call to their customer service line. So, I made the call and got help. I didn't have to wait in a queue and the person on the other end of the phone spoke English as their first language.
Summary: I have been using my BT600 black mouse everyday with my Mac Book Pro unibody for a year and I have been very pleased with it's performance. I purchased it after a Targus AMB08US Bluetooth Laser Mouse for Mac failed out for the box and was promptly returned to Amazon. Radtech's customer service is very good too.
Summary: Against the tepid reviews that can be found online I purchased this mouse through the amazon marketplace. The item arrived in 3 days. The bluetooth connectivity, full size, rechageable batteries and usb charging cable were all selling points that attracted me. I never got a chance to test the batteries or connectivity because out of the box the secondary buttons proved to be too difficult to depress and VERY loud once they did finally click.
Summary: I bought this mouse Feb 26 2008 I have several devices with built in bluetooth, 2 PS3s, an Hp Vista Media center laptop, a handheld Sony Vaio UX280P and a Samsung Omnia Cell Phone, all of which use a bluetooth mouse and keyboard. This Mouse has some good features that unfortunately don't make up for it's poor quality construction. First the good. The Rechargeable Batteries last about 3-6 Days 8-16 hrs a day use.
Excerpt: While I love the design concept for this mouse, it has rather chinsy build quality and absolutely horrendous lag. The cursor lags behind the mouse by a very noticeable amount - it may be good enough for casual web browsing or something, but it is absolutely unacceptable for anything more...
Summary: I bought the Radtech BT600 to replace a wireless Apple Mighty Mouse. The scroll ball had become unresponsive, and I can't live without scrolling. The scroll wheel on the Radtech BT600 worked well, but nothing else did. First of all, the Bluetooth connectivity is spotty. I haven't had a single connectivity issue with my Apple keyboard or Mighty Mouse; they've been connected to my iMac for over a year and neither has ever dropped a connection.
