Pros: We have about 10 of this units at my work. We have experienced many power outage from one last less than 1 seconds to 30 minits. All of them always switches to UPS mode quickly, and never had trouble with any of the computer , PBX, etc.

Cons: not much.

Overall Review: we modified some of them to connect to 100AH Gell Cell Battery, now our UPS last about 10 to 20 hours. This UPS is heavy duty.

Pros: Good display , portable. GPS work goods. Good LCD display with good contrast , easy to see outside. GPS receiver is fairly sensitive, it work fine while putting on passenger side seat. worked inside of house also. The units does not have to be placed on top of dash board to receive GPS signal like some others.

Cons: electric compass does not work. I calibrated several times, but sill does not work. can not calibrate temperature parts of weather reading. I can not change first digit 5. USB cable connector could fit 180 degree off. need to buy additional $150 downloadable map to see any detail road. without that it only show major roads. $150 downloadable map is must.

Overall Review: if you are looking for units to be used in a car, look for other products.

Pros: simple to use by anyone accurate map in Orange County , CA here. easy to search restaurant, bank, etc.

Cons: need to install map software by computer, require tedious registraion process like windows XP

Overall Review: I will buy another one, if you are not familier with computer , let someone else do set up for you, and buy 1GB MicroSD flash ram to store entire USA map.

Cons: not much
