User Reviews about GR-213-USB: Holux USB Mouse GPS Receiver GR-213 for PC

I recently purchased the Holux GR-213 GPS mouse device for use with my mobile weather platform, and it works very well, with the notable exception of the installation. I run Windows Vista Home Premium x64 edition, and the installation only supports 32-bit systems. Slightly disappointed, I needed to run around the internet and install another serial driver to even interface with the device. I ended up using the "Prolific USB-to-Serial Comm Port" driver, and now the device works perfectly and is fairly precise. It is very compact, and has a long USB cable for placement wherever you need it, and, as advertised, is waterproof. It has a very good lockup time, ranging from a few seconds to around 10 seconds. It provides programmers with plenty of information, including your GPS position, sattelite positions, altitude, speed information, and much more. All in all, this is a very good device, and I do advise any consumer to purchase it. -- Installation difficult on 64-bit, but very good nonetheless.

The holux GR-213-U comes with a fairly long cable and is advertised as water proof. I have not tested this. However, I did break this thing apart to mod inside a netbook. I couldnt get reception there. I removed it.. soldered a new usb cable to it and then electric taped all over it.. Now it plugs into a regular sized usb again and works perfectly! Picks up a precise location in seconds on a warm start or half a minute from a cold start. Comes with monitoring software which gives coordinates, altitude, time, date, and much more I dont need to use. Works with other mapping software.

This thing has an internal battery and memory. If you use it often it will remember satellite data and pick up signals on the double. Truely awesome. Very small. Should be cheap. -- Why you should buy this (for 45 dollars or less)

I have used five of these now in boat navigation laptops for myself and friends. Very fast lockup, it always has a position before the nav software loads. Very sensitive, while others are having to stick their GPS out side this one is receiving in the cabin. I like the fact it is powered by the USB port and doesn't need a separate battery. -- Holux 213 USB GPS
