I have quite a lot of scrap and thought it would reduce saw repeat visits but unfortunately it's pretty much useless. I've tried working with this several times with two different tape measures and it's clumsy and a waste of time and money. Says there is a choking hazard - yes, I choke every time I see it in a trim bag and remember spending $13 on it. If I still had the packaging I would send it back today. Not every gadget that hits the market is worth it and this is proof of that. save money
