Obviously when you buy those inserts they have their own double sided tape on, but although it feels strong as foc at first, the rain eventually gets to it.
Once they spring a leak you get fogging in between the insert and your visor which can obviously become a problem if it's in your line of sight.
When they're airtight though they work brilliantly, and the very slightly thicker double sided i bought works for much longer.
This time i made a point of making the join of the tape in the bottom left corner as well, it's all a bit Blue Peter but it's such a useful insert because it very slightly tints in harsh sunlight as well as the no fogging, and it turns headlight and brakelight glare into single lights.
I've had this one at least 4 or 5 years now, i just keep renewing the tape and reusing it.
With a tilt of the head the Sunax sunshield puts a proper dampener on very bright sun glare.
