I bought this for the sole purpose of using Trackmaster for Android to record and analyse my lap data during trackdays and race weekends using my HTC Incredible powered by Android as the recorder. I could not be more pleased with the results! Absolutely flawless execution, battery lasts all day, .1 second refresh gives a very accurate point to point calculation of speed and time, and average geo-position accuracy is 7ft!!! works with my Mac OS X using google maps and google earth as a blue tooth serial device, and works with my Win 7 laptop using just about any GPS software available.

I am very happy with this product.

NOTE: As you see in the title of this review, this GPS is not for iPhone/iPad users unfortunately.

Many of the reviews on this product come from people who have not compared it to alternativse you might be considering.

We use this for a business application, and for that reason, I've researched/tested all of the Bluetooth GPS receivers that I can find.

One key thing to know when buying, do your research on the type of GPS chip. Like so many electronics these days, there may be hundreds of variations, but you only have a few core technologies below them. This unit uses the MTK II chipset, which is arguably the best chipset going, for a non-integrated GPS. In other words, there is one unique piece of hardware as of this writing, the Galaxy S2 phone, which has a more modern chip with some very unique features and power-saving technology; however, that chip is not practical to use in this type of GPS receiver and for that reason, a competitive solution with that chip (SiRFstarIV) will not likely be offered for sale.

We've been using this model for about 14 months with great results. I'll list the reason we found it superior to other solutions:

1. Optional 1,2,3,4,5,10 Hz updates. In other words, you can choose to receive GPS updates from 1 to 10 times per second. If you've ever passed a turn because your GPS was 50-feet behind your location, you understand how important high-frequency updates can be. Using a smart-phone, you are limited to one update per second (at best). The reason for this, GPS polling is very tough on battery life. The 1/second option will save battery life if you don't need a more finite resolution.

One note on this feature.

This units works as advertised, and I recommend it. However, "as advertised" can be a little misleading.

Contrary to what one reviewer said, it is the 1 Hz switch position that gets programmed via the software, not the 10 Hz position. The 10 Hz switch position always gives 10 Hz.

Be aware that the 10 Hz position disables differential GPS, i.e., WAAS. You get faster update but each measurement is less accurate. For small intervals of time, presumably the WAAS correction does not change much so that tends to offset that issue if all you are looking for is changes, not absolute values. This characteristic is true of many GPS chips out there, so (as nearly as I can tell) don't bother looking for one that has WAAS at 10 Hz. This unit is definitely state of the art in small, portable, Bluetooth, long-battery life, high update rate, GPS receivers.

The GPSView software has a nice feature that, in addition to setting the update rate for the 1 Hz switch position, allows you to select how often *individual* sentences are transmitted. For example, by setting RMC to 1 and GSA to 5, with a 3 Hz update rate, you get 1 GSA sentence for every 5 RMC sentences (a big backwards intuitively), with the RMC sentences at the 3 Hz rate. 5 is as high as you can go. You can also turn off individual sentences by setting the value to 0. This is very handy for reducing the transmission bandwidth to just what you need.

Does what is is supposed to do. The battery lasts a very long time. I use it with my Motorola Droid Razr Maxx running ICS and a app for tracking autocross racing. Very quick to get a signal.

Bought this to work on a custom GPS application for android devices. This thing is great! The GPS data just streams as a raw NMEA stream, and is thus very easy to parse and use.

The only problem I had with it is that some of the bluetooth GPS applications (that translate a BT device into a fake location service) on the market don't actually send all 10hz, so I had to write a custom one for myself.

I use this with a AK-N7000: Bluetooth GPS Adapter for Nikon DSLR D7000 and a Nikon D7000 16.2MP DX-Format CMOS Digital SLR with 18-105mm f/3.5-5.6 AF-S DX VR ED Nikkor Lens. I have used it for about 10 hours off the initial charge (which is via a USB cable to its included lithium ion battery) -- I was worried that it would run down while I was using it but it seems to run forever.

I ran into one small problem: I don't get geotagging on about 5% of my photos. Not a huge problem since the other photos have the location set, so I know where I was. I don't know if this is an issue with the camera, adapter or GPS receiver.

Overall I am happy with the product and it does what I want: geotag my photos.
