How customer reviews and ratings work

Customers say

Customers like the signal strength, battery life, and lock of the GPS. For example, they mention it's an excellent Bluetooth GPS receiver, it acquires a satellite lock faster than any GPS they've ever used, and it saves batteries on their iPhone. That said, opinions are mixed on performance, accuracy, ease of use, and speed.

Reliable - contrary to other reviews

Reviewed in the United States on August 18, 2021

Verified Purchase

I was SOOOO AFRAID of purchasing because of the negative reviews of acquiring a signal, but I made my purchase after flying with a crewmember who had the device.

After 16 north Atlantic crossings and 4 domestic legs the "Good" Efl had performed flawlessly.

Positioned in the rear window of the 777, with soft velcro on the unit and the ever-present hooks tab on the lower-right shelf of the window, the unit acquires a position quickly, connects to known devices automatically, and is easy to pair to a new crew iPad.

(the only PiTA is deleting shared guest iPads from memory - but that's relatively easy)

Battery life is exceptional: 10/12 hours to/from Europe. Two 8 hour crossings without a charge. Two 13 hours duty days with two-legs each.

I highly recommend this unit.

***update - Jan, 2023***

Now after using the unit for 19 months I can attest to almost perfect reliability. The battery life is exceptional - 18+ hours (VIDP to the US). Even when flying through areas of known GPS challenges (think Turkey and Afghanistan), the unit maintains a reliable and accurate signal.

I still highly recommend.

I've been looking for a replacement GPS logger for when I travel. I've not been too impressed with the quality of software used to download and convert the data down to a PC on the devices I've used before. This product works great and uses a USB drive interface to access the GPS data already in GPX format. I'm actually using it with a Chrome OS tablet. There are ways of manipulating files on the device to perform all of the functions I've needed. There is a way to change device settings using a Bad Elf web site to help make changes to a data file which can then be placed back on the device. I rarely need to do this so needing internet access for this isn't a big deal to me. It looks like I could hand edit the settings file if I really needed to. Removing old logged data is also possible my moving a data file that corresponds to a GPX log from one directory to a another. It's not as simple and clean as a software package to do everything but it's nice that I'm not dependent on someone maintaining a PC software package. I don't replace these devices very often so being future-proofed is a good thing. There is one minor caveat though. If you wait too long to download your GPX data from the device it won't have enough internal memory to create the GPX-formatted files from its internal format. I just dumped my data daily and then removed them. Doing this daily also allowed me to set a pretty high sampling rate too. Also, a lot of these features required searching around the Bad Elf web site or sending an email to their customer support. I did get my questions answered very quickly.

Great for recording travel, hikes, etc.

Reviewed in the United States on May 2, 2017

Verified Purchase

This unit is an excellent/compact GPS receiver for tracking walks, hikes, drives, flights (except, apparently, in Boeing 787s, whose windows block the signal!), etc. It is very flexible in its settings, and allows you to make very detailed GPX records of your movements. If you select 1-second updates, the resulting GPX file(s) will be huge for tracks of any significant length. There are ways to reduce the size of the files, but in my case, I wrote my own custom software to do it. The results were quite good, and the files were, on the average, about 1.5% the size of the original, and lost very little detail. I still have the large original files in case I need the extra fine detail. The battery life is excellent, although the battery level indicator does not appear to be linear. It's a good idea to charge the unit as soon as the first bar disappears. It acquires satellite signal quite quickly, at least compared to older models of GPS receivers, and its accuracy is very good. My only real complaint with this item is that the screen apparently scratches very easily. Mine had annoying abrasions across the screen before I even got to use it on a hike. However, it has spent most of its time since then in a case, and has not shown any new signs of wear.

Update: 2022-08-20

As of today, I've had my Bad Elf GPS Pro+ for six years. I've used it mainly for recording hikes, walks, drives, and flights, and archiving the tracks. Many of them end up on my website, showing exactly where those hikes, etc. were. Overall, it has worked very well for these tasks, so far. I did have the occasional lockup (rare, but it happens), and lost-signal events (mostly on aircraft). Signal loss occurs most often when the unit is not held close to a window on an aircraft (even letting it dangle in front of you from its lanyard, while seated in a window seat is often not sufficient to maintain a reliable signal). Also, as noted above, GPS receivers don't tend to work where windows are shaded (such as on a Boeing 787, and trains in Norway, for example)...and that applies to all receivers, not just this one.

I did have a problem a couple of years ago where the unit would occasionally (sometimes "frequently") not "find" any satellites after a long time searching. Customer support tried hard to fix the problem, which seemed to magically go away a few months later (I don't use the device much between trips). There have been a couple of firmware upgrades since then, too, and I've had no further problems with that failure. I almost always use another GPS receiver (often my iPhone) as a backup, just in case this sort of thing happens.

Very recently, I've noticed a decrease in, or complete lack of, GLONASS satellites being detected. I'm going to assume for now that this is because of the conflict in Ukraine.

Battery life is a major advantage to this unit. When I first bought it, and for most of the following six years, it has easily run all day on an overnight charge. Just in the past few days, however, it has ended the day with only one of the four battery indicators still showing. While one can obviously just pull out a backup battery or plug into an available USB power outlet where available, the full convenience of not having to charge the unit at all...or needing its charging cord immediately available...seems to be coming to an end.

My original review still stands, although my comment about the non-linear battery indicator may not be all that accurate any more. It does seem to go down fairly smoothly over time. Maybe it improved over the years of firmware updates? Also, I'm not sure how my unit got abrasions on its display back when I received it, but there is minimal additional scratching of the screen since then, despite being used on numerous hikes, drives, etc. I do normally keep it in the convenient carrying case (not included with the receiver) that fits the unit snugly, and generally protects it from the overall abuse of banging against rocks along the trail...and whatever else happens while traveling.

The Bluetooth connection with my iPhone seems to have become rather unreliable lately. Pairing can be really flaky at times. Other than being frustrating and annoying, it hasn't become a serious problem...at least not yet. If you use the device as input to an important app on a smartphone, this might be a bigger problem. I usually only need the connection to transfer tracks from the Elf to the phone.

Note: For a long time, I had difficulties saving files from the iPhone app (Bad Elf app) to Dropbox. It turned out that my light/dark mode settings resulted in "Save" being a very light gray against a white background during the day. If you're trying to save off an archived track to Dropbox (or anywhere else on that sharing page), tap the upper right part of the window, and it'll work. Or wait until dark mode kicks in, and you'll be able to see "Save" again.

Summary: this is an excellent choice if you are looking for a small, lightweight GPS receiver for the purpose of archiving the tracks of hikes and other travel. I've owned many GPS receivers, and this is easily the most convenient one for this purpose...and of course you can use it for other things, as other reviewers have described. Happy sixth "birthday" my GPS Pro+!

2nd UPDATE 2023-06-18

The GLONASS problem was solved by a firmware update. Version 3.0.0 fixed that, and positioning is very good again.
