(More customer reviews)Update December 2010:
DO NOT leave this plugged into the GPS for extended periods when not being used.
It consumes a small amount of power, and will flatten the GPS's internal battery within a few days. There was an even worse problem in one of my cars which was not used for several weeks. It left the car battery TOTALLY flat when it and the GPS were left plugged-in to an un-switched 12v outlet (even though the GPS was switched off).
I still rate this item as ***** (5 stars) - now that I know how to easily avoid a flat car battery. Just unplug it!!! All 5 antennae I have bought are still working fine (as is my now-ancient Nuvi 350).
Update December 2009:
I continue to be impressed and bought 2 more to give as gifts. AND No! I have no personal interest in the company (unfortunately). Improves speed of signal acquisition in my Garmin nuvi 765/765T 4.3-Inch Bluetooth Portable GPS Navigator with Traffic - especially noticeable when the GPS has not been been used for many days. Again, thoroughly recommended.

Update April9 2009:
I was so pleased with this item that I bought 2 more so that they are permanently installed on my cars.

I came across this item while browsing Amazon for reviews on new GPS. I needed to replace my 30 month old Nuvi 350 which was non-functioning - displaying the dreaded "Cannot Acquire Satellites" error message. The 2 reviews on this antenna both stated that its use had resolved this issue. Further investigation confirmed similar results with other comparable antennae.
I had returned a Nuvi 750 because its performance was inferior to the 350. Seeing that the cost of both the antenna and shipping was minimal I decided that I did not have much to lose by ordering one.
When it arrived, I connected it to my 350 and dumped them both on the passenger seat. - My hopes were high but my expectations were low.
In a very short time I noticed that my old 350 (previously destined for the garbage) was now fully functional. Further investigation revealed that signal strength is far higher that it had previously been. Signal acquisition is also very much quicker.
The antenna itself measures 1-3/4" x 1-3/8 x 9/16", has a 10' 1/8" diam. cord and has a powerful magnet for easy routing and exterior attachment. Since I am getting such good signal strength, I shall probably place it permanently above the dash where it will attract less unwelcome interest.
My other pleasant surprise was that it had arrived in Maine (from Texas) 3 days after placing my order.
When I finally replace my Nuvi 350, it (and this antenna) will continue to be used in our second car. My new GPS (maybe 765?) will be ordered along with a second antenna - hopefully from the same seller (if not Amazon.com itself).
One caveat:
The antenna's plug could be improved. It is tiny and difficult (very hard on finger nails) to remove. I plan to attach a more substantial grip (maybe a 1/2" diameter plastic disc or similar shape) using epoxy glue to eliminate this minor problem.
This is not enough of a problem to reduce my 5-star rating.
FYI:
The Nuvi has a direct connection for an antenna rather than through its quick-disconnect mount (a design upgrade would be a major improvement!!!) therefore this item must be unplugged whenever removing the GPS.
