Device is good but do not waste your time on its Data Viewer which is junk.

Summary: I used to have a BT-Q1000ex which was able to operate at 10Hz, but I lost it on a train ride in Vienna. I need one to geo-tag photos, but do not want to spend my lunch money on it, so I got the cheaper BT-Q1000xt instead. The frequency of xt model is only half of ex model, but it seems more than enough for tracking location of my photos. BT-Q1000xt works as good as BT-Q1000ex for my purpose. It acquires satellite fix fast and hot start takes only a second or two.
Summary: Works good. Descent price. Much better alternative to a camera with built-in GPS. This little guy will operator for 13+ hours on a charge. Only big problem is the software for managing the GPS logger is anything but intuitive.
Summary: Does what its supposed to do, tracks GPS coordinates. Battery life great. The problem I encountered is with the QTravel software provided with the unit. Software is able to capture data points from unit, but when I tried to export to a GPX file so I could import into Lightroom I found the resulting file was missing large chuncks of data.
Summary: I bought this to use on my motorcycle to re-trace good roads. It is compact, has good storage and battery life. Software is pretty limited, but usable. My primary complaint is that it worked well, but not for very long. After about 1.5 years (8-10 trips) it won't charge the battery anymore, and Windows won't recognize it when it's plugged into a PC.
Summary: this unit seems to work. read through the manual about 10 times, and combed the mfg web site for info required info (password) to pair the bluetooth with my droid phone. after hours of research and fumbling, turns out the bluetooth "pairing" password code is 0000......this info was found in a manual for a totally different device on the MFG web site. the manual does not have ANY info regarding use of blue tooth or the 5hz gps option.
Seems to disconnect for no reason - software crashes often

Summary: I have high expectations with this after comnparing the reviews of many similar devices on Amazon. My usage is to geotag my photos and to record the tracks I took on the park trails. I usually walk for 2 hours for 5-6 miles each weekend. After using it for 3 weeks, I have decided to return it since I may have gotten a bad unit. My rating would have been at least 4 star if HW works OK (see problems I saw below). + The unit is very easy to use. ++ Very well built.
Summary: Used this on a Beijing trip few weeks back. Couldn't log any track on aircraft. Lots of drift. Good battery life and storage capacity. Accompanied software not polish. Cannot write gps data into raw photos.
Summary: I've used the device for a couple of weeks now and for the most part it's pretty accurate. From the hardware point of view, it does what it's supposed to do and I have no complaints. The point-of-interest button is an interesting feature letting you tag a location when you are there that will show up in the track data later. The biggest downside to this device is the software - the quality is well below par.
Summary: The 5Hz "update" rate is deceptive on the BT-q1000x. It did not even cross my mind that a GPS device that could take a reading every 5th of a second wouldn't be able to do the simple task of writing that data to the log at the same rate. I would have paid the extra $50 had I known the eX was the one that actually logged at 5Hz. This was the main reason for the purchase as I use the unit for skydiving tracks that last only 10-60secs.
