I previously purchased a Bentech TK-913 Mini tracker and am writing this review based on it. The tracker is overall quite lightweight and I have been using it for my Traccar server. It works, but it only makes sense to use it if you are sending a command to send a location on a regular basis. For example, the most practical interval is one to two minutes, but the battery will drain in about ten hours, which is impractical. If you are looking for a tracker to use with your trackcar server, I would recommend the Bentech TK-913 Mini
Comes with a backup battery and charger so you can charge the spare battery and prepare it for replacement
Tracker is not waterproof
It comes with a plastic case into which the tracker can be inserted; however, the case is not very practical, as it needs to be removed almost every day, and the part where it fastens with a clasp can deteriorate over time
You must insert the largest size card. Although many SIM cards are made in this size, there are also smaller versions, so care must be taken when inserting them to avoid them separating into nano SIMs

My fifth, complete satisfaction
I've been using it for 7 years
Accurate to within one or two metres, very accurate locator.
I charge permanently with a powerbank, so I don't worry about the battery life on the bike and in the car. I check it once every six months or so. Hidden on the wheels so that a thief has no chance of finding anything.
For those who get short battery life on their integrated battery - know that you have it set up wrong. The endurance data in the manual, plus or minus small variations for individual modes, really fits.
If someone keeps sending data to the server every 30 sec, even when the device is not moving, he can't be surprised if it lasts a day, or even just a few hours. In the case of a weak GSM signal, the device naturally consumes a huge amount of power in this mode. However, there is no single reason to use this mode. If the device is not moving, it will fall asleep - and this is the correct setting. By shaking him or calling out to him, he'll wake up.
Consumption when stationary is practically zero.
In this mode, connect to the car battery in the car. But only in this.
As a SIM I recommend Kaktus - 1GB plus 100 SMS per month (Data is needed for online tracking on the map, SMS for sending alarms from the locator to your phone - low battery, unexpected movement, instant location, etc). The price is 100, - + 100, - per month, when using the "recharges" of Kaktus (2x per month) 100% extra credit, so a total of 100, - per month for everything - and this I already accept. Watch anytime for almost free. At the moment (May 2025) there is nothing better in the Czech Republic.
Anyone complaining about dysfunction and problems just misunderstands what is going on. And no - I have nothing whatsoever to do with the manufacturer or the seller.
All problems are related to bad settings.
I've never been betrayed by one.
I haven't really found it, maybe just a chargeable map registration (one time fee), but I understand that the online map tracking server doesn't run for free. There is no need to register if you just need an immediate response from the locator about its position when it rings. You ring the locator, it hangs up after the second ring and sends the position on the map, coordinates, time of sending and battery level in SMS.

I spent over two hours setting it up, but it kept showing the address of a Chinese hotel.

works - if I just use it in always-on mode
Very light and small.
Understandable controls, when rung from the mobile phone it sends back a link to google maps with the current location via SMS.
Non-functional "standby" mode, i.e. the device saves and battery and only wakes up on a ring and sends the location. It never manages to find enough GPS satellites before going back to standby, so it sends the last detected position long out of date. So standby mode is unusable.
In "always on" mode, it eats battery, so it doesn't last long.
It is controlled and set only by sending commands to the device via SMS. High SMS consumption
Need a SIM with a convenient SMS tariff.
Very brief instructions, the device has e.g. a memory card slot, why, we do not find out.
It has a permanent location tracking mode via the manufacturer's www, activation required for 500kč with data SIM.

Used as a simple locator in case a motorcycle is stolen by an occasional crook (for a pro with a jammer, it's pretty nice, of course). It must be installed in a dry place (not waterproof) and can be connected to a flashlight (via USB cable). In normal operation, it is quite sufficient to connect to the live branch only when the ignition is switched on, so as not to accidentally discharge the battery during a prolonged shutdown (it seems that if it is connected to the on-board mains power, it will not sleep - the consumption came out to me about 30 - 40 mA, which is not quite enough, while the built-in battery without the mains power will last in sleep mode for at least a week, maybe even longer). Deployment is easy, just insert the SIM card and go. If you only need to occasionally detect the location on request (ringing), you can use e.g. A VF SIM card with a "zero tariff" and zero cost, yet it works even when roaming outside the EU (which data often isn't). Only outgoing SMS with location is paid. ATTENTION - about 5 minutes after the position query it will fall asleep and on the next query it will return WRONG the original position, i.e. it is necessary to request the location twice and only the second one is correct (perhaps there is a possibility to set the re-sending of the location, this would solve it automatically). I have not tested the device in continuous position tracking mode via data transmissions.
Small size and weight
Easy operation
Zero fixed costs in SMS mode
Relatively good battery life
Permanent connection to an external power supply
SOS button
Not waterproof (IPxx)
When requesting a position in sleep mode, the first position transmitted is incorrect
The motion alarm will respond (regardless of any smaller distance setting) up to 200 m from the "lock" point
