MulWark 1/2" Digital Torque Adapter Converter(12.5 to 250.9 ft-lbs) with Tire Pressure Gauge | Buzzer | LED Flash | LCD Backlight | Memory Function | 50h Working Time, Calibrate Digital Torque Wrench

Are you psychic? Then this is the tool for you because that’s what you will need to operate it.The instructions are horribly misleading and incomplete.Let me start out by saying, eventually the product worked fine for me. The lack of stars is due only to the fact that the instructions do not make it easy to figure out how to use it.The instructions say you will see “trACE” or “PtoP” when you turn it on. Instead, mine showed tire pressure units. Instructions say to change units you press the “P/T” and “M” buttons at the same time. It just cycled between tire pressure units. I had no idea how to change it to torque. I tried actually attaching a ratchet and socket. No dice. I sent it back as defective.When I got the replacement it worked exactly the same way. I thought I must be doing something wrong. I tried again and again. No dice. I handed it (with instructions) to my wife and asked her to try it because I thought I might be missing something. She could not make it work.I noticed in one of the reviews the person said they would never remember how to get it to display tire pressure. They had to press the “P/T” button and power button at the same time. Now, there are warnings on the Amazon listing page that tell you not to press those two buttons at the same time “when powered off” or it will go into calibration mode. They don’t tell you how to recover from that so it seems like it’s a catastrophic event. The “when powered off” is the key phrase here. You MUST press these two together WHEN POWERED ON to get it to toggle between tire pressure mode and torque mode. The instructions which come with it will also tell you as an important safeguard:“Do not press the ‘Mem’ and power button together. Otherwise, the system will enter into calibration mode”All of these warnings are telling me not to start pressing buttons randomly in the vague hope that it will start doing what I want it to.In fairness, after they tell you how to use it as a torque wrench, they do tell you how to switch it to use it as a tire pressure gauge. It’s about ⅔ of the way through the instructions. If a person read past how to use it as a torque wrench and read that part, they might figure out that they can toggle it to torque by pushing those two seemingly unconnected buttons (“p/t” and power but only after it’s powered on) at the same time. But that’s a stretch.I found I could make this thing work. After selecting torque mode and the torque value, I found that pressing the “Mem” button seemed to save the selected torque value. That is not in the instructions but at least it quit flashing.Some might say that 2 stars is a little extreme as a rating since the thing works. I maintain that if it’s unintuitive to use and the instructions don’t tell you how to use it, it’s a useless tool. I feel like it was just luck that I eventually figured out how it works.

I wanted a digital torque wrench because click type mechanical torque wrench seems easily get out of calibration. This budget friendly digital torque adapter fits the bill and uses AAA batteries. It seems to be accurate so far much better than my mechanical torque wrench.But it is bulky so it doesn't fit tight space very well. It's also tricky to switch between tire pressure to torque mode and I had to read the manual to figure that out. The battery compartment is accessed by loosening 4 screws, but that makes it very difficult to change batteries. It also doesn't recommend rechargeable batteries. If you understand all these limitations, it can be a good torque wrench, but I would get a better one if you work on vehicles for a living. For me, I only use it once a while and it works well and came with a storage case.

Works fine as calibration tool. But as a standalone will take a lot of getting use to as once reach your desired setting it still over torque which item you are torquing. Personally I still prefer my clicker style torque wrenches but will use this to make they stay calibrated.It is also clumsy to use in tight places especially when you having another tool at the same time.

Product did not work. New batteries. Display turned on. Presented the word PASS. But did not function. Could not select setting. Applied pressure by hand to the wrench extension I attached and all of a sudden the indicator started increasing on it's own without being able to stop it. You can feel when applying hand pressure on the wrench attachment to the device that the internal components are not well made. Not a solid feel to the device. Returning product.

I don’t have way to check the accuracy but rug nuts that tighten by tire shop was beeped at 90 lbs-foot. That’s good enough for me. I didn’t want to send another couple hundred dollars for 250 lbs-foot torque wrench and I don’t have lots of extra room in tool chest. It’s very compact. I just missed the sound and feel of clicking when tightening the hardware. So far it was good buy!!
