I have a vibra screed with some use on it with a 14ft blade works great i just don't use it im not doing the pole buildings no longer what a fun tool all you need is a guy on the trucks shoots placing and the other guy on the Shockwave and pushes big rock off the surface and brings it the cream makes a big difference on edges and crawling the slab there's probably a total of 15 max hrs on it. I paid 3200.00 a few years back
