    It really works!

    posted by crisgoet on 01/22/2013 Certified Owner

    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:
    Those plastic stones do really turn colored when exposed to UV light, such as the Sun (even in cloudy days), and back to transparent when indoors, exposed to standard lighting. They take just 10 seconds to fully respond to UV and 2 minutes to go back withou...
    Cons:
    The silicon wire that holds it together is thin and could be broken if the strip is abused, but you can always replace it by ge...

    Cellphone strap

    posted by Ariaofmarina on 12/16/2012 Certified Owner

    Involvement:General (knows how to use it) - Ownership:1 day to 1 week

    Pros:
    Good as a cellphone strap. Have yet to see if it works under UV ray as the opportunity hasn't presented yet, but it doesn't matter. If it does work as described, I'll buy this again as gifts for others.
    Cons:
    Nothing right now.

    Surprisingly Usefull

    posted by filekb on 11/11/2012 Certified Owner

    Involvement:General (knows how to use it) - Ownership:1 week to 1 month

    Pros:
    These beads are small, light and easy to carry anywhere you want to being them. They seem to actually work on UV and not just on the brightness of the light like some of the othe UV detectors I have tried. On a bright summer day I took the beads outside a...
    Cons:
    Seems to be a little too sensitive. Good to tell you if there is UV, but not really usefull to tell you if it is moderate or h...

    Useful UV protection tester

    posted by cmarino on 07/04/2012 Certified Owner

    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:
    The colour changes almost immediatly when exposed to UV radiation. It is useful to test sun glasses, UV lights and sunscreen. Another good thing is that it is easy to use and can be attached to your phone, bag, etc.
    Cons:
    Mine came with a blue plastic pendant which I think could be a bit smaller. This accessory is made in a cheaper quality plastic...

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Nice little gimmick that responds to UV radiation. Put it in UV light, the beads change colour. Remove it from UV light, the beads turn white. Useful for - testing sunglasses - testing suncream - warning for UV light - Nice gift
    Cons:
    Cons: Does not give a strong indication of the strength of the UV light. It'd be nice if blue meant 'there is UV but it's OK a...

    Involvement:General (knows how to use it) - Ownership:1 week to 1 month

    Pros:
    Nice looking strap with the cute beads. The beads change from colour immediately after exposing them to sunlight, very cool and lovely! Very easy to use and instructions are not needed at all! The quality of the beads and the strap are good.
    Cons:
    Though the actual colour changes do not really match the given indications, everything works and so there isn’t really a con fo...
