I have such a screwdriver now the 4th year and I must say that he has not left me so far down (use the device at about 60 tire changes per year)
When I bought it to me at the time I was looking for an affordable alternative to a pneumatic screwdriver. The unit was in the performance category then by far the cheapest and I thought to myself so that you do not say anything wrong.
But the device: Solid build quality, the only thing that bothers is the black plastic ring which dissolves directly in use (have my walk there anyway no real benefits can be seen). Plastic and aluminum housing of good quality (here and there lacks the conciseness which also no longer bothers me). Powerful motor, but I doubt that the full power 450nm. Think there are 300 - 320nm implemented. But so far can solve all the wheel nuts. Engine but quickly warm.
Coal can also be replaced simple. The screwdriver, unlike brand appliances add some weight but this is perfectly fine because the solid material maintenance at the expense of the weight.
Among the supplied nuts I can not say anything because I've used directly Already inserts.
Conclusion: For private use absolutely sufficient.
