I obtained four of these having previously bought an inferior product from Coopers of Stortford, who then didn't reply to my complaint over the clear lack of display.
Apart from an initial lack of adhesion I received speedy advice and support from Colour Changing Products and so flexed the indicators to a curve similar to the bottle (The magnetic backings are adequate but could be better). They now adhere and read as advertised and should give advance warning of an empty bottle, where there isn't other means of determining this.
I have previously bought a DeWalt cordless drill and router, both of which are excellent tools. When my 20 year old Makita planer smashed on a hidden screw, I looked everywhere for a similarly large w x l bed and found nothing available. The DW677 is certainly smaller and not as bulky or heavy as it's stablemate. It's capable of shallow rebating having a spring loaded cover over the spindle edge. I give it 4 stars because it lacks a dustbag or proper carrying box to complete the package.
