Review on 🏗️ EternaBond 2.5 lb 2-1/2" Wide Curved-End Ball Bearing Steel Roller - EB-R125R: Durable, Heavy-Duty Roller with Enhanced Control for Optimal Performance on Various Roof Surfaces by Maurice Cunha

Yes, the tool is expensive. However, it is well designed, made from very high quality materials and very well built. And yes, it's hard, a lot harder than you might expect. However, this weight makes this tool better than competing products. The weight of the tool, combined with the pressure applied by the user, helps activate the chemicals in EternaBond so they adhere to the surface it is applied to. don't mind spending the extra money on the right tools to keep it in working order. If you are using EternaBond tape, purchase and use this tool to apply it properly.
