What are your thoughts on Side Planers?

[Troutster]

I picked up 2 of these on advice from someone in the know?. I haven’t tried them yet but I liked how the arms fold into the center for storage, and they can lock out to either side. They seem really nicely finished and pretty versatile. Take this all with a grain of salt because I haven’t ever used a planer board before. Can’t wait to try them in a couple of weeks.
