FIRSTINFO Digital Torque Screwdriver, Dual Direction 0.44-4.42 in-lbs. / 5-50 cN-m / 0.51-5.1 kg-cm

Netter Drehmomentschlüssel

Have no concerns; this is a serious tool. I'm very happy with this purchase.

Muy buena herramienta para trabajos de precisión y un tanto especiales, sus características permiten un manejo minucioso, solo se necesita saber los torques del apriete en cuestión. Lo único malo es que la herramienta no trae manual ó instructivo para su uso, claro no es complicado usarlo pero si por ejemplo sacar las punta y poner los torques no se vale estar con el ensayo y error, pues es una herramienta de precisión.

Great torque screwdriver, has a certificate of compliance. I use it for torque tests on toys I make to ensure compliance to Australian standards. I would buy again (if I need to)

We got one of these at work for determining our needed torque on some semiconductor test sockets. This tool really rocks, and beats the pants off the digital "toy" torque screwdrivers. This tool will actually cam-over when you hit the target torque, so you cannot over-tighten. It is easily adjustable, although it can be a small pain to hold the gold adjustment ring while locking/unlocking the torque setting. It fits whatever 1/4" bit you have, so it doesn't really limit you. NOTE: For those who don't know, ALWAYS return a torque-device to its lowest setting when you are done. Don't leave it at a particular setting, or you risk the spring mechanism taking a "set."
