Great little tool!
Instruction are clear and easy to understand - This is JUST a torque wrench - does not come with any attachments - - In my opinion, it's best for use with bolts up to about 1/2" - if possible, get the bolt or equipment manufacture's specs on max torque. My purchase was for M8 (3/8") bolts at 12Nm One CAN order a wide variety of accessories (personal experience), and, as it's a standard 1/4 inch drive, most users will likely already have most everything that will be needed Once the tension is set, ( up to 150 inch/pounds [in-lb] or 16.9 Newtons/Meter [Nm] - ) there is no need to "read" anything - When the set torque is reached, there is a slight "bump" that is felt through the handle. (if your hearing is better than mine, you may hear a "click") The instructions suggest - wisely - to practice a bit to "get the feel" of proper operation. Personally, as I am getting old and my eyesight is getting bad, I prefer this method - - Because I don't have to struggle to read a scale or a display to know when I've reached the desired torque. (Being a bit of a gorilla, I have a tendency to snap bolts off - especially small bolts (1/2" is "small" to me) - so this tool is a great damage saver) Setting the desired torque is also very simple. Although some folks who are not familiar with the technique may have a short learning curve, it's just a matter of turning a knob until marks line up. The instructions have very clear pictures. The settings are in both ASE and Metric, so it is not necessary to mess around with conversion tables or calculators - although a conversion table IS included with the instructions. One precaution though. This is an all meta tool - if using on electrical equipment (which is my usage) it would be wise to wrap electrical tape around any accessory that may be at risk - and keep it in good shape. Shock hazard aside, a short circuit can cause extreme heat and serious burns. This precision instrument comes, as it should, in a nice hard fabric storage case with a tight zipper - the instructions fold nicely in the case - the tool is held in place in a pocket on one end, a Velcro strap on the handle. This case comes in a plastic bag and in a nice sturdy cardboard box - I store this combination in my home - not the garage or tool box - as befits a fine scientific instrument. One last thought - described in the instructions - my grandfather, a custom jeweler and watch maker, taught me that springs - and this device depends on a spring - springs have "memory" - that is, if left wound up, they loose their temper (as if they got angry and being cooped up too long) and 'forget' what they are supposed to do. SOOOoooo, always change the setting to the lowest point when puting this tool aside - especially when putting it into storage. Otherwise, it will loose accuracy over time.

A must for bike maintenance
I wanted to have a backup torque wrench for my bike tool kit, so I found this one more than covers the range I typically use between 2 and 15 Newton meters. The dual markings in both Nm and inch pounds are essential to setting correct torque. For the price, you get a protective case with good instructions and useful conversion charts. I used three of my fixed torque keys to test calibration with the Tekton and results were in spec. This is a good buy, friends.

The markings are very easy to read as is adjusting the torque setting
Opened up the zippered hard-side case and was immediately impressed with the feel, markings, handling of the micrometer adjustment and smoothness of the ratchet mechanism. Not a big fan of quick release buttons on ratchets as it requires a hollow drive wheel that weakens the drive plug. Could have left that out of the design and it wouldn't have mattered. Proper maintenance of the ball bearing with a drop of penetrating oil periodically prevents having to pry sockets off. However, it's not much an issue with a torque wrench that won't be expected to break stuck fasteners loose. The markings are very easy to read as is adjusting the torque setting. This wrench has the newer style slip ring collar that you pull down to unlock the handle to turn it in one inch-pound increments. I've never encountered half inch-pound specs that would call for a wrench spanning this one's 10-150 inch-pound range. If I did, I'd simply round up or down and be done with it. Even at the 10 inch-pound minimum, 0.5 inch-pound is 5%, nearly within the wrench specs and close enough for practical purposes. Those working on stealth aircraft with composites, spacecraft, and nuke weapons, requiring 1% or better accuracy wouldn't be using a Tekton to begin with. Tested its operation using a 1/4" drive breaker bar with an 8-point 1/4" socket (for square head nuts, bolts and screws). The "click" is easily felt and unmistakable throughout its range, even at the 10 inch-pound setting. Did not notice any difference in forward or reverse. There's a popular misconception that the "click" is intended to be audible. While it is audible, depending on ambient noise level (some shops are noisy with machine tools and ventilation fans), it's designed to be felt by the hand turning the wrench as one roller bearing on a beam rolls over the top of a fixed roller bearing on a heavy spring causing a "break" of about 10 degrees or so in the turning of the wrench. Release pressure on the handle and it snaps back. The fabric covered zippered semi-hard case is a departure from the common blow-molded cases most wrenches come with now. It's not going to put up with the bashing and banging bouncing around in a box with other steel tools would subject it to. I don't store or carry torque wrenches in that manner anyway. They're (semi-)precision measuring instruments, not breaker bars or sliding T-handles, and should be reasonably protected. Some may take issue with the case and its robustness compared to a blow molded. I don't. I've handled, used and owned numerous tool brands over the past 45+ years, including high end Snap-On, S-K and Proto that I still own and use. This is an impressive torque wrench, most especially at its price. One could easily spend 2x - 3x or more on a bi-directional 1/4" drive micrometer click wrench and not get much if anything practical at all for substantially more money. Final Comments: A torque wrench should NEVER be used like a breaker bar to break loose stuck or corroded fasteners, most especially a bi-directional like this one. It can easily ruin its calibration and can permanently damage the click mechanism inside the wrench (even on a uni-directional). Proper use is turning slowly and firmly as the fastener tightens until the wrench "breaks" about 10 degrees or so indicating the torque setting has been reached. It's much more feel than audible, especially in the level of ambient background noise commonly found in many garages and shops. Using a torque wrench is not a racing team pit crew contest. Achieving proper torque with one reliably and repeatably is a deliberately methodical process - with the wrench being turned only from the middle of its handle. Might seem counter-intuitive, but choking up above the handle, or worse yet using a "cheater pipe" to add length to the wrench won't accurately torque the fastener. I've seen this demonstrated on a torque calibration machine and the reason has to do with the design of a click wrench and its internal beam mechanism; they all use the same mechanical concept internally.

Clunky
It's a bit clunky. The ratchet slips when you are torqueing and I'm not sure I trust the accuracy. It seems very hard to turn the adjustment and it has a nasty detent once every turn.

Works great
A very useful torque wrench to have in addition to a full-size 1/2" drive torque wrench. You don't want to be torquing down sensitive low-spec bolts, such as those inside an automatic transmission, with a 1/2" torque wrench. Large torque wrenches tend to sacrifice accuracy near the low-end of their working range. I can't comment on the accuracy as I haven't tested it, but this wrench worked flawlessly when I torqued down the bolts on my transmission valve body during a transmission filter replacement. I believe my wrench was accurate as the bolts that hadn't loosened over time either didn't move at all or just turned a hair when torqued down. I much prefer how this wrench securely engages to the chosen setting. No risk of accidentally loosening the knob on the end and changing the torque setting as you work. I see people complaining about the weak click on these, but I think it's audible and tactile. Of course it's not going to click as loudly or firmly as a full-size torque wrench, this thing is tiny. Torque wrenches work off of a spring mechanism. Smaller wrench = smaller springs = less feedback. If you want your torque wrench to scream at you, then feel free to pay extra for a digital one.

¡Está bien calibrado! / It is acccurate!
Compré esta llave dinamométrica después de verificar que mi vieja llave estaba fuera de calibración por más de 30% y era imposible de ajustar. Verifiqué la calibración de esta llave Tekton en todo el rango usando una báscula electrónica, una regla y algo de Matemáticas. El error en toda la escala esta dentro de +/- 4%, como dice el fabricante. I purchased this torque meter after realizing that my old torque wrench was way off calibration and impossible to adjust anything closer than 30% of error (beware owners of torque wrenches branded as SETTE). I measured this Tekton torque wrench just after arrival, I found it accurate within +/- 4% for the whole range, using an electronic scale, measuring tape, and some math.
