Like Hippy says removing the light bit of the Dinotte is a breeze, it's the velcro bit of the battery back which is the pain, it doesn't take forever to take it off but it definitely feels more like a couple of minutes than 15 seconds, maybe I'm just impatient.
On balance I still think the Dinottes are fab, best lights I've ever bought, one problem I have had with the rear light is that convenient as the o-ring mounting is, while it holds the light to your seatpost very securely, it doesn't do so rigidly, so while I've never worried that it'll fall off I do have a tendency to catch it with the inside of my leg and push it around the seatpost so it doesn't point straight back but off at an angle. Not a major problem but still a bit of a niggle.
