All I can say is if you love to paint and are obsessed with not having gaps in your moldings and walls but taking forever to fill and paint them - this is it your tool. Firstly, it's very well built and will last a long time, no crappy plastic is going to break. Second, it's super easy to use: just wring out the bottom of the tube you're using (works best with clear coat), add your color, stir, switch bottoms, and you're done. I can't believe I waited or spent so long to find a tool like this literally hours before painting.
