Very good 7 in 1 - Sun 7 In 1 Survival Tool

Pleased with the Sun 7 In 1 Survival Tool. Magnifier is great for reading and assume good for fire starting and does unscrew from main housing. Compass must unscrew first. If Magnifier is lost, unfortunately can't reattach compass as thread size is different. Liquid filled compass responds well and has somewhat oversized N arrow to help poor eyesight (wish it was some more oversized). Wish compass N arrow was luminous or glow in dark - would add much value. Storage chamber is nice, but useless if lose the magnifier. Thermometer seems ok but protective cover needs more glue as I partly dislodged it during strong-hand-test just now (I can easily fix). Whistle seems ok but a bit too high pitched and I would want something to stuff in my ears. Lanyard and generous attachment seem good & strong-enough. Striker not tested.
