Nice plunge saw, purchased with the Einhell guide rail and it works just fine. Great for cutting up boards and certainly seems accurate.
The saw has two adjusting **** to ensure that it fits snugly on the track to avoid deviation.
I have had this machine for about a month now and have found it to be accurate and efficient in use. Set up was easy, instructions were clear. Its ideal for a small pro workshop or enthusiastic hobby worker. Well built, cast iron table, it all just feels 'right'.
