I have had the HI-302CF for a month or so now. I think it works fine. I bought the kit with the PCMCIA adapter and the external antenna.
Some of my experiences:
Power: It's thirsty. With the standard battery in my Axim it runs for about 2.5 hours with the screen brightness turned all the way up.
Thankfully I anticipated this, and got the 3400mAh battery for the Axim. Theoretically that should last about 5-6 hours.
Reception: Without the external antenna it works fine outdoors. I normally get 6-8 sats. Sometimes even 12 sats at once. Indoors it seldom works, unless I attach the external antenna (also located indoors), then it usually gets 3-6 sats.
In the car: Works best with the external antenna mounted on top of the dash just under the windscreen.
Precision: Works best when it can see at least 5 or 6 sats. From my experiments I would say that the precision is within 5-10 meters. If less sats are used, the precision drops to 10-20 meters.
Altitude is less precise. On average it seems to be consistently about 40 meters too high compared to the official measurements in my home town.
TTFF: Reasonably fast. Normally 45s to 60s for a cold-start... 10-30 seconds for a warm start. Under 10 seconds for hot start.
Those times are measured when it has a good view of the sky.
If I start driving before it obtains a fix it takes a very long time... Sometimes several minutes.
Reaquisition: When the signal is lost (for example driving under a bridge) it usually reaquires the signal within a few seconds
Design: There is a gap between the top of the Axim to the bottom of the bulky part of the GPS, as if it isn't inserted all the way. Looks a little fragile.
I personally dont like the greenish color of the unit...
The LED is placed on the left side of the unit. I would have preferred it placed on the top, so it would be visible from more angles. It is also hard to see the LED in bright daylight.
PCMCIA (With adapter): Works fine on my laptop.
All in all I have to say that I am very satisfied with the unit.
