'Book Mystique Review: Three Little Mice From Radtech
by Charles W. Moore
Trackpads are OK, and I’m quite happy using them for short stints, provided that they are either “tappable” or have a lighted button action. I can’t abide stiff trackpad buttons, like the ones in my WallStreet and Pismo PowerBooks. Happily, both machines support trackpad “tappability” for clicking and dragging, so one is rarely obliged to use the miserable buttons.
However, for production work I much prefer a mouse or trackball. That’s easy enough when in desktop-substitute mode, but what about when you’re in the field or on the road? From the get-go, many portable computer users have packed a mouse around with them. In the early days, this meant putting up with three aggravating factors - the mouse cord, the tracking ball which frequently needed cleaning, and the necessity of a mouse pad.
The advent of optical mice solved one of the issues. The erstwhile maintenance routine of removing and cleaning mouse tracking balls now seems almost a bit quaint, and many optical mice will also work on a variety of surfaces - even a pantleg - although my preference is still to carry a mouse pad. But there was still that pesky, tangle-prone cord.
Consequently, Bluetooth wireless mice make particularly good sense for laptop road warriors, eliminating cord tangles and the necessity of plugging and unplugging the mouse cord. Frankly, I fail to see much advantage in a wireless mouse for desktop use, with its requirement for periodic battery changes or recharging and the minor annoyance of wake-up lag , but for portable computing these are lesser evils.
Bluetooth mice are available in a variety of configurations, but our review subjects today are a gaggle of very small mice designed specifically for mobile users. The Radtech BT500 mini Mobile Bluetooth Mouse that we reviewed here separately last winter has now been joined by a rechargeable model and two small form-factor mouse stablemates - the RadTech BT100 and BT300 rechargeable Bluetooth mini mice, both, like the BT500, being very compact and light three-button units suitable for taking with you on the road to use with a laptop.
All three mice are targeted primarily at laptop users who are looking for an easy-to-take-along mouse for road warrioring, and are small enough to fit in a shirt pocket.

BT300
Getting the battery compartment cover open proved a bit more of a challenge at first with the BT300. As with the BT100, access to the battery compartment is through the back of the mouse housing, but in this model, the mouse button panel accounts for about three-quarters of the housing’s length, and the removable portion that covers the battery compartment is rounded and contoured, so it was tricky to get a grip on it to pop it loose.
Turned out that pressing down on the back of the button top panel releases an internal catch, but there is nothing in the packaged instruction sheet to indicate this.
Better documentation would be helpful, but once I had it figured out, the two rechargeable NiMH cells (AAA) slid in easily, and it only took a few seconds. You can find more information online at:
http://www.radtech.us/Products/Default.aspx#CategoryBluetooth
Note: Radtech warns to only use rechargeable alkaline or NiMH cells in these mice, and only to connect the USB charge cable with NiMH cells installed in the mice (ie: don’t try to charge alkalines using the USB cable).

- Smooth tracking, maintenance-free 800 dpi optical technology

With these rechargeable mice, you never need to get stranded with dead batteries again: Just connect attach the included USB charging cable to your computer and let the batteries charge while you continue working with the equivalent of a wired mouse. The BT-mice scroll wheel doubles as a charge/connection status indicator (blue/purple while connecting, red while charging, and green when fully charged). The batteries charge very quickly - taking under an hour for the indicator to turn green. The two mini-mice use a cable with an audio-jack type miniplug on the mouse end, while the BT600 uses a cable with a standard USB connector of the sort used to connect digital cameras to computers or printers.
I liked the feel of the BT300 scroll wheel better than the one in my BT500, but the one in the BT100 is the least satisfactory of the lot, having a “stiff spot” that might work out with use.
Tracking is very light and positive, and I have no complaints at all in that regard with any of the three.
Tiny and weighing in at a luggage-friendly 66 and 65 grams respectively with batteries installed, the BT100 and BT300 are easy to take along, and like the BT500, they even work well on the palm rest of my 17” PowerBook.
The appeal of the BT300’s styling, with two scalloped mouse buttons flanking the central scroll wheel, is a subjective judgment, and I prefer the (non-rechargeable) BT500’s looks best of the three Radtech Bluetooth mice I’ve tested, but they are all reasonably attractive. The scalloped buttons do tend to cradle your fingers in a way that is probably more conducive to sound ergonomics, and I like them better than the shorter, more conventional buttons on the BT100. For a very small mouse, the BT300 is surprisingly comfortable to use, although button click pressure required is a bit heavier than with the BT500. I would rate the BT100 the least comfortable of the three mini mice in the family. It’s not bad, but just doesn’t feel as hand-friendly as the BT300 and BT500, with less smooth tactile surfaces and a more angular shape.
These mice will automatically enter sleep mode after 2-3 minutes of inactivity; click a button or move the mouse while in sleep mode and the connection is seamlessly restored in seconds. An easily accessible power switch, located on the underside of the mini-mice and the top of the BT600, allows the device to be manually powered down for extended periods of non-use.
Connecting the BT mice is simple - no drivers needed for Mac or PC. OS X’s Set Up Bluetooth routine (select from the Bluetooth menu) found all of them quickly and with no hassle.
To activate the mouse connection, make sure Bluetooth is active on your computer. In OS X, check the “Discoverable” check box in the Bluetooth preferences panel, and also “Show Bluetooth Status in the Menu Bar.” On the mouse itself, make sure batteries are installed, turn the power switch on. You may or may not have to press the pairing button on the bottom near the optical sensor. The scroll wheel should glow blue to indicate that the mouse is in “Discoverable” mode.
From the Bluetooth menu, select “Set Up Bluetooth Device” and then follow the instructions. When asked for “Device Type”, select “Mouse” If you are using the mouse in conjunction with a Bluetooth keyboard, make sure to switch the keyboard on first, then the mouse (after the mouse has been paired). If asked for a pairing code, enter 0000 (4 zeros). Note: don’t press press the pairing button once the mouse has been paired. If pressed, connection will be lost and pairing process will need to be repeated.
All mouse buttons are fully application assignable with no additional software, but you can install RadTech’s free RadMouse configuration driver (see below) and take even greater control of your digital domain.
BT500
The BT500 is a very small mouse, measuring just 85.2 mm x 50 mm x 32.6 mm. This tiny cordless critter pops easily into a shirt pocket, and even with its two AAA batteries installed, it is feather-light. I have long fingers, and find some compact mice uncomfortable to use, but this one is engineered to be operated with the mousing hand and forearm resting on the support surface while the mouse is manipulated with your fingers, and I’ve found that quite comfortable. The “Satin Rubber” coating on the bottom segment of the mouse housing provides a positive grip, although all that is needed with this mouse is a feather-light touch.
As is fairly common practice, the BT500’s three buttons are actually left and right buttons plus a clickable soft touch silicone composite scroll wheel. The BT500 mouse’s scroll wheel button function can be assigned to individual applications that support device button mapping, as well as OS X Exposé.
The action of the left and right buttons is comfortably light. The scroll wheel click is stiffer, and it has detents rather than the smooth scroll action I would prefer. The BT500 mini Mobile glides smoothly and effortlessly on the mouse pad or other contact surface thanks to low-friction nylon feet.
Another area where the be BT500 mini Mobile shines is in ease and convenience of access to its battery compartment. The palm rest segment of the case just quickly pops off, making battery insertion a literal snap.

Overall, my favorites of the three are the BT300 and its non-rechargeable BT500 fraternal twin - unique as tiny, light, but full-featured and comfortable mice suitable for road-warrioring. The BT-100 - well, one had to finish last I guess. I just don’t see the point when you can get the slicker, smoother, better-looking and more comfortable BT300 for a couple of bucks more.
