They were originally blue. I guess in line with their corded range,
then they changed colour...
however, the new model incorporated micro adjustment (circled, +++²)
The colour change was probably because
Ryobi didn't want to be mistaken for that other crappy blue line products some dare to call...
Bos¢h!
Still have a few blueys,
uses the same battery...
Still, router/trimmer circle cutters are ho-hum... it's the unplanned extent of the dust extraction, that blew me away.
If your first cut is too short... Take the second cut from the longer end... LBD
