This is the second of these tools that I have purchased. The first was about 2 years ago and it's still giving excellent service. I purchased a second to save having to swap bits quite so often. It holds extremely small drill bits accurately and it is so much easier with the chuck than with collets that you have to keep changing. Highly recommended.
Seems to be a well made tool and ideal for all those fiddly little drilling jobs when model making, far better than trying to get an electric rotory tool into said jobs and less risk of doing some damage.
