Review: Funciona perfecto - Dude en comprarla por algunas reseñas que vi. Pero en mi caso funciona tal cual la descripción de la lámpara. Es pequeña y podrás usarla para viajar si así lo deseas.
Review: Perfect - I bought this to use with antifreeze dye leak detector fluid. Yes I found 2 very small leaks that pressure testing did not reveal to the naked eye. But I could smell it for the last 2 years with very minimal fluid lo loss, less than 1/2 liter per year 12,000 kms per year. Small seepage coming from 2 water pump bolts. Note: Don't replace water pumps at -15 celcius without some source of heat...lol!

夜釣り用に買ったのですが、それ以上にキッチンやらトイレやら汚れがよく見えますのでついついイタズラしちゃいます。以外だったのが水道の蛇口汚れでした。この値段で買えるのであればもっと早く買えば良かった。かなりコスパいいですね。
