David Great light, very bright with good battery life. Really pleased with it, happy to recommend.
arrkayteee Brilliant ‘day-bright’ light. My only concern is the securing o-ring seems a bit thin.
Mr FUJITA コンパクトで且つ、明るいので私の要望にマッチしたライトでした。大変満足しています。
Raul Great quality and design. Very powerful light. Was thinking to buy the larger back cobber but for me the mid back cobber is good enough.
