It seemed very good to me when I gave the car to my ex. To check if it went where it said... it didn't go there after all, that's why it became an ex. Very good functions all, the only downside is that it drains the battery if you leave the car unused for a week. I had gone to England and on the last day before returning it stopped sending me notifications, I knew it was in its place from a relative of mine. These things and in general it is very accurate though

The battery lasts very little, about one hour. The product did not include a second battery and the case with the magnets. The stamp was given correctly.

It doesn't always give the correct position.
It may get stuck in one position and always show that until you move.

A friend recommended it electronically.
I installed it in the machine.
In a position to be perfectly stable.
Not getting wet, not getting dusty.
With a permanent charger.
All SMS commands work fine.
Every now and then I take it off the charger to check its autonomy.
It lasts at least 3 days.
Shock and movement commands are flawless, immediate, and accurate within 5/10 meters.
GPRS is unnecessary for me.
If something happens, the stamps it provides with the shock alert are more than enough.
I would like it to have a fixed cable plug and not a USB on the unit.
6 months of flawless operation.
Size as small as a matchbox

I have it for a year and it is quite reliable in terms of capabilities and accurate in tracking. Programming via SMS is relatively easy. As for the battery, if it doesn't have a GPS signal, it depletes quickly, otherwise it can last 5-6 days. One solution is the special USB adapter 12v-5v for permanent installation in the vehicle's battery or using sleep mode with vibration detection on.

Tragic..battery lasts for about 3 hours!! Only the GPS is accurate indeed but its battery barely lasts 3 to 5 hours..I've changed three batteries and still gave up on it..put one with a permanent power supply

For its price, it is good. The GPRS works properly and has a small deviation. It consumes very few Kb, so it's not worth sending a message and being charged for no reason. The battery is small and requires an external charger, with all that entails for the car battery if it stays outside for many days. If you don't have it, it doesn't last. You get what you pay for.

I'm coming back on 23/1/20 after many attempts, it constantly gets stuck in GPRS mode and the application doesn't show any change in position... After many hours of refreshing, it might show...

It is possible that it needs a stronger antenna.

Simply unacceptable...don't even bother buying it.
The manual is unclear, there is no installation order, everything is a mess.
And even if you manage...the signal is never stable, never correct, everything is wrong. Of course, you get what you pay for

I have it in my possession for a few days, but it is enough to draw some conclusions in order to evaluate the device. The positives are that it works well in SMS mode, meaning it notifies you via SMS and sends you the coordinates in link format, and with the Google Maps application on your smartphone, you can see where your car or any other object or person with the GPS tracker is located. Another positive is the battery life, which in mine lasted 4 days with one charge (12 hours on the first charge, approximately 8 hours on the next), and the low battery SMS notification also worked properly when it reached 25%, which I consider very important for the device's operation.
As for the negatives, I include the help mode (SOS) function, which activates without reason or cause at random times, as well as the other modes that either do not work at all or are very difficult to use.

The worst GPS tracker ever made. It constantly sends zero coordinates, and out of the five pieces, you manage to find one that works well, but it quickly shuts off and you lose your belongings! The most unreliable product on the market!

I messed up... don't buy it... what the kids say is true, the battery drains quickly, you charge it for 8 hours and it only lasts for 3...

Good product and you get what you pay for. Don't expect to get a tracker with 800 or 850mAh battery for 10 or 12€, let alone with a second battery or charger.
I paid 28€ for what I got, but the package included 2 850mAh batteries, a charger, cable, charging dock, waterproof case, and most importantly, the 2018 SOFTWARE WITH SLEEP MODE for energy saving. It easily lasts me a month and I have it on a boat!

I have it for over 3 months, it works perfectly, it has many operating parameters such as movement zones (radii), vibration detection, speeding violation alert, and it notifies all of these immediately via SMS. I use it for a boat and its battery lasts about 5-6 days.

Problematic from the beginning - unreliable and with very poor construction quality inside out - it randomly shuts down without reason and there is no communication with the tracker.

Well, this particular product is the worst and most terrible thing that is available on the market. It turns on whenever it wants, it turns off whenever it wants, the lid doesn't close properly, resulting in the battery falling out and the GPS function never worked. The shock function and the move function never worked either, so if your vehicle gets stolen, you cry with black tears and you don't notice anything. The battery life is terrible, it only lasts for 8 hours with a three-hour charge. It's ridiculous

Luckily, I found a manual on the internet....it works relatively well but in disturbances it turns off, there is a gap between the battery and the device.....

Everything works perfectly.
The GPRS works perfectly fine, you just need to follow the instructions step by step.

Regarding its functionality with SMS, it works flawlessly. As for the GPRS status, personally, I couldn't make it work, either because I didn't configure it correctly or because a subscription payment is required.
