Review on ⚙️ MulWark Digital Torque Adapter Converter - 3 to 59 ft-lbs with Tire Pressure Gauge & LED Display by Gervan Mauldin

I already have several torque wrenches, both mechanical snap-on, mechanical skip and electronic with built-in pressure gauge. I mostly don't use regular keys :). Why do I need another torque wrench adapter? Because I do :). I mainly plan to use it to check and calibrate my mechanics. Also, it's the only tool that can handle up to 250 ft lbs of torque, none of the others I have can do that so I can pair it with my wrench for HEAVY POWER DURGE if needed. .First impressions. This digital Mulwark torque gauge comes in a nice, sturdy and small plastic case. Inside is a mini screwdriver and a compartment for extra batteries. Batteries are already pre-installed in the device. Replacing the batteries is not that easy, you have to use the screwdriver provided to unscrew the four small screws on the back, then remove the battery cover, then insert the batteries, then repeat in reverse order. I highly recommend using a magnetic screwdriver for this instead of the one provided to avoid losing the screws, they are so small that if they fall on the floor they are almost impossible to find. I have to say that this design is clearly bad, there are much better and safer ways to hold the batteries in place without screws. Also, the screws are short self-tapping screws and they thread directly into the plastic casing of the device, ensuring they don't strip the threads in the plastic in the future. If they wanted to use screws they would have to at least put brass taps in the plastic and use screws instead. As I said, the design of the battery compartment is very poor. Exploitation. It probably has the worst user interface I've ever seen. When it arrived the first thing I heard was a squeak in the molded box, apparently the box was so tight that she pressed her buttons and the device turned on and spontaneously went into calibration mode. There's no way to lock the buttons, and removing the batteries before inserting them into the case isn't an option, as it takes around 10 minutes to do. There are 6 buttons on the device and one of them is not used for anything, it is empty. At the same time, 3 buttons have a dual purpose depending on how long you press them, and other functions require pressing two buttons at the same time. Why waste a key and invent all these weird keypress combinations I don't understand. I'll never remember having to press the P/T button and the power button at the same time to get into tire pressure mode, why not use that blank button instead? Seriously, you'll have to refer back to the manual every time you use this device, it's so unintuitive. In addition, the buttons tend to be accidentally pressed when holding the device in your hands, e.g. B. if you attach it to a wrench, there is a high possibility that you will accidentally press some random keys, which may cause some random functions to be used. And the last complaint is that the device doesn't remember your last set torque and you have to set it every time you try to use it. It starts at 100 and if you want 250 you have to hold the button for a minute to scroll to 250 as the number increases in decimal places. As I said, the most terrible interface. A calibration certificate is included in the scope of delivery, which lists the serial number of the device that matches the device. It is calibrated at three different levels: 68, 204 and 340 Nm. Each deviation was much less than 1%, but I had 0.88% on my device once. I don't think these certification results are very good either, I've seen much tighter tolerances on more expensive instruments. I might be fine with 200 ft-lb of torque, but unacceptable for the smaller ones. The certificate contains the date of the test and the name of the tester, but no signature. Other thoughts. This device can also be used as a tire pressure gauge, which is useless and another design flaw. I will never use it and would rather not have it at all. The problem with this sensor is that the device is bulky and doesn't fit properly in the tight spaces between the car's wheel spokes, so you can't even use it. Even when it fits, you have to apply vertical pressure to it to open the tire valve and make a tight connection between the pressure gauge and the tire valve, and this device is very uncomfortable to hold and press on the valve no matter how hard I try I had air leaks and bad tire pressures, and I ended up having to pump the tire back up. A completely useless feature that shouldn't be here at all.*** Conclusion ***No, I don't recommend it. It is inconvenient, the interface is terrible, the batteries require a screwdriver to change, it is difficult to work with, the buttons tend to press themselves, the measurement error is up to 1%, and the tire pressure sensor is simply unusable. I really wanted to like this device but I can't deal with all the problems. The design is bad. Two stars and only because it can measure up to 250 lb-ft of torque. Benefits: 1) Maximum torque 250 ft-lb. Cons: 1) The UI is terrible. 2) A screwdriver is required to replace the batteries. 3) Difficult to use and impractical. 4) Buttons tend to click on their own. 5) Measurement error is up to 1%. 6) The tire pressure sensor is just useless.
