Effetto Mariposa

Nuts and bolts will never feel the same again.
Mike did warn me on the calibration needed for a torque wrench but its just an esstential tool that you cannot do without.
The selling point. Effeto guarantees an accuracy of +- 4% deviation for 5000 clicks before recalibration is needed. If you do the maths, assuming I tighten an average of 10 bolts or clicks per week, every week. That equates to roughly 500 clicks per year, which means the wrench is good for an least 8-10years!! Man, thats more than enough for me.
The other advantage, as you use it more often, your hand 'learns' the torque. You can just able feel it before it hits the 4Nm mark/click and you just ease off. So frankly, 10 clicks/per week is really more than you need.
The bits are also standard sizes that can be replaced at any hardware store so fret not if you lose your fav No4 and 5 allen size.

Looks pretty darn small. It the torque loading high enough for seat post clamp n handle bar clamp..

Just use them on "sensitive" parts which contain carbon.

Dont worry too much about the alum bits. Like disc brake calipers n levers.

Yup, think it goes from 2-16Nm. U only need 4-5Nm for carbon stem/seatpost. Got the ParkTool beam style torque ($60) for cassette and crank.
