Rated 4 out of 5 by Excelente produto. Fácil de carregar e não entra água nas partes internas. muito bom o produto 16 August 2014
Rated 3 out of 5 by Great light but bad strap The light output is excellent, but Mine fell off and light was lost. Bad strap. 15 August 2014
Rated 1 out of 5 by The rubber strap breaks. Nice light until the rubber mounting strap breaks then you cannot attach this light to your bike. Don't risk it. 25 July 2014
Rated 1 out of 5 by Плохая фиксация Это был бы отличный фонарик - удобный, яркий, если бы он не отстегнулся во время поездки и не потерялся. 01 June 2014
Rated 1 out of 5 by Dont Buy this is the second Knog light where the silicon strap has broken under less than expected conditions, nice light but not worth the trouble 01 April 2014
Rated 4 out of 5 by Very Bright Light This is a very bright light. It is very easy to put on the seatpost. The recharging mechanism is a little bit of a nuisance and I can only do it with my laptop USB port as it won't go into my normal PC. This is probably the only negative point I would make about this product. 31 October 2013
Rated 2 out of 5 by Great but fragile Great light, bright and can be seen from quite a distance. Rubber band tears easily. 3rd one I've had replaced... Moon Comet is much better. Brighter and more durable. 25 September 2013

Given that (1) different people and manufactures express the measurements of height, width depth in a different orders and (2) that the measurements in whichever order do not match those on the Knog.com.au website what are the measurements for this light ?

Please do be explicit. I am particularly interested in the width as I do not like having my legs rubbing against the light when it is attached to the seatpost.

Thank you.
