Its the same as the better Sealey SM5 with quick release vice except ram.
Had mine in 97 lasted about 18 months before the 6 main guide bearings went. Gone are the days when 3 blades for a tenner, now around £18 each and not even bimetal vari pitch, one reason never put the new bearings in. Chews blades up quicker than can put one in, but thats setup i cant get round to doing.
The other concern and has been problematic time and time again.
The vice ends short of the blade something like 40/50mm, meaning shortest you could cut would be 50mm plus amount gripped in vice and packer the other end of vice!
Even worse when cutting angles.
Personally i would have a look at one in the flesh, ok for longer lengths.
