Great product and very useful when I need to drill a hole in my cabinet under the sink with a small spacing that I can't drill straight into, so that's when I got this one used a right angle and the result was fine, I don't know how I could drill a hole in the bottom of this small cabinet with this product because I couldn't get my drill into this cabinet. Thanks to this product I can now drill a hole in a spot with a slight angle. The build quality is good for its size.
