"I like the presenter, and the viration of time reminder wonderfully improve the time controlling."on by billjin
Pros Good size, good key position, good holding feeling, vibration not sound helps me greatly
Cons Loose 4 direction keys and unsafe case for usb receiver
Summary My new job is to give presentation and show prefessional so I bought one. And I am satisfied by it except 2 points, and I don't regret I didn't buy the Targus and Logitech, because it is more difficult to buy them in China market.
The size is smaller than my imaging, but it's really proper size and leads to the keys are very easy to be touch. Mode selection key is very clear. Power switch can make me to know cleary it's on or off. The holding feeling is good, appreciated for the processed skin, not slippy. The vibration reminder is better than sound, I like it. And the LCD of rest time really can improve time controlling in professional way, or I have to look at the watch occasionally. And it can set 2 vibrations, one is warning mins afore can be set, and the 2nd is final for "time is up", very good design.
But, 2 points I have to mention. One is that the loose 4-directions button. In presentation mode, it makes the + and - keys are easy to be double clicked, which makes me a 3-5 seconds break in the presentation. I think the loose design is for mouse mode. The second is that the soft case is small and the usb driver is designed to be inserted in the small "pocket" on the side. I am always afraid of loss of the usb receiver by accident.
Finally, I really think it's a good tool for presentation. By the way, it cost me RMB 480 (value added tax included), updated 1:7.8 rate, it cost about USD 62. More expensive than the price listed here, right? I think so, especially it is obviously made in China.
