I intend to take mine to work also to verify the accuracy.
Well I beg to differ I bought this exact one 4 years ago, and use quite a bit at home, I take to work regularly to check it and it is still in, I always back it off after use and only use it to torque up and never use it to break off nuts (y) (y) (y)
I bought this last year in store for £19,99 so this is a cracking deal. Used it few times on my car, predominantly wheel nuts, sub frame and suspension components. It is reasonably well made for the price and DOES come with calibration certificate - little leaflet inside the box. Not sure how accurate it is and I wouldn’t use it for head bolts, but you get your money’s worth easily, just need to think about what you’re going to use it for.
Sorry, I guess I didn't make my point very well. You said "Guessing << aldi torque wrench < expensive one" - what I was trying to say is that a badly calibrated or seized torque wrench may be worse than guessing. I'd actually rather use a standard ratchet than an uncalibrated torque wrench of questionable quality. Your point on QA is interesting, because it does raise the point that the ones Aldi are selling may be QA or calibration failures! It does look very similar to the Clarke one I have, which was about three times the price, but mine did come with a calibration certificate. Of course they may be just the same - but without a calibration certificate there's no way of knowing. Absolutely agree on making sure the tension is off before storing!
Got one last time in stock. Seems good quality and works well.
