Question: warranty??
Document: works as they should
this is a great protective set for working live of with the power off if u r a pro and work obligatively live then ok but if u r not and don't no what u r doing then make sure the power is off
the grip feels very confortable, the screwdrivers are a Little bit heavy. but the quality is very good, be carefull to use the right driver for the proper screw, because the metal of the driver if very high quality and you can easly damage the screw head...
so far so good. I've not used much yet. I like the grips and they seem to be high quality.
one of the best
looked at Wera, Craftsman Professional, Easton etc, and got the Wiha's. They seem very nice, with lovely big handles. The tips are sharp and grip the screw heads well.In truth, I do not think you would find either Wera, Craftsman Pro or any other mid-market screwdriver bad. These are nice, but no nicer than my other Craftsman Pro or Gear Wrench screw drivers.
good fat handle to hold, nice case to hang on tool box, good product for the money, has a flap to keep to tools clean
Your hands will also feel better too at the end of the day , even if you use them all day. Other brands have left my hands hurting at the end of a long day, but never these.
You can find plenty of insulated screwdrivers that are much cheaper but they are no where near as good as Wiha. I have bought wiha before and I have never been disapointed. They are comfortable to use even after a long day's work.
Wow, what can I say, WiHa makes some damn good looking and very functional tools. Hands down the Best you can buy in my opinion.The price here on Amazon was great.Would definitely recommend.
