Pesos & sense is a new, weekly feature about gadgets or applications that we feel are worth spending our own hard-earned money on. While we enjoy playing around with several new gadgets on a weekly basis, there are some that really catch our attention and we thought it would be good to point them out to our readers.

I love Bluetooth products. The fact that the technology will most probably be eclipsed in a couple of years by something else that works at higher speeds but is just as frugal in using battery power (see wireless Firewire, for example) hasn’t stopped me from building up a small collection of Bluetooth devices that I use in a personal area network: an Apple PowerBook , a Palm Tungsten |T2, an SE T68i, and a BAFO headset.

I had long wanted to get a Bluetooth mouse to use with my laptop. The logical choice was the Apple Bluetooth Mouse but I was turned off by the large size and the lack of a second button and a scroll wheel. So, when the RadTech BT500 turned up in local stores, I rushed out to get one (P3,500 at Games&Gadgets at Greenhills Theater Mall).

I’ve been using it for a couple of months now, and am very happy with it. It’s the perfect travel companion, and works as advertised. The scroll wheel feels a little sluggish compared to my wired Logitech Mouseman Traveler, but I really have no major complaints.

Some caveats though, for potential buyers:
- The mouse is small, and may be uncomfortable to use for people with really big hands
- The bottom part of the mouse has a rubberized coating, and after a couple of weeks of use, it was dirty (madungis)
- Battery life is short (about a week’s worth of use). I ended up getting two sets of rechargeable batteries after computing that six months worth of AAA alkaline batteries would cost me as much a two sets of rechargeables and the charger.
