    Pros: Just working, nice looking gadget for everyone.

    Cons: I didn't find any cons - it is just so simple build :-)

    Other: Just nice working gadget for adults and kids :-) It is not measuring unit, but very simple testing unit, showing intensity of process. Worth it's money. It is so light, that can be added to any traveller's stuff, or beach equipment.

  • It really works!

    posted by crisgoet on 14:59:52 G1T 22/01/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    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 without it. Fun and cute! It's even cheaper than other standard phone stripes sold in the streets.

    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 generic sewing thread in case this happens...

    Other: Great little gift for girls too! :P

    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.

    Other: Probably makes a good gift, but uncertain if it will work as described. Will definitely buy this again as gifts to people when it does work as described.

  • Surprisingly Usefull

    posted by filekb on 01:33:53 G11T 11/11/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    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 and they turned really dark purple indicating high UV index. I then put the bead behind my car window which is supposed to block all UV, and the beads turned back clear, even thought the light was still really bright.

    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 high levels.

    Other: Well worth the price for a basic indicator of whether there is UV or not. I.E. good to test your sunglasses.

    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 than the rest of the strap.

    Other: I recommend it, it is useful to test your sun glasses and a nice accessory to carry on with your belongings.

  • Nice gift, unusual gimmick

    posted by cadocado on 07:27:49 G8T 05/08/2011 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: 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 and red was 'danger'. It's not like that. Is not indicative to different sorts of UV light. It's probably sensitive to UVA, UVB and UVC.

    Other: Nice gimmick, nice as a gift, it feels somewhat magical to see it change colour like that.

    Involvement Level: Expert (understands the inner workings)

    Pros: -It is very small, very easy to carry. -The results are really clear and pretty accurate. -I use it to test my sunglasses UV protection and it works very well. -It looks good! -When it is in contact with UV rays, the color changes really fast! -It is really simple to use... :p

    Cons: -It is a little bit long before it loses its colours...

    Other: I recommend it, you know, for people who like to see if their glasses really have a UV protection...

  • Great little bracelet

    posted by matrix-neo on 21:43:37 G9T 02/09/2009 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: This is a nice looking bracelet that is awesome as a gift, it has two in one function, it's a beautiful looking bracelet and it will let you know when there is too much UV radiation
    The beads will go darker in color depending on how much UV light you receive, so the bottom ones go like a smoky color and the top ones will go dark red if you get a lot of UV radiation

    Cons: Works just as advertised, but maybe they can make it a little longer?

    Other: Nice gift idea

    posted by Mialee on 14:30:52 G6T 21/06/2009 certificated customer

    Involvement Level: Expert (understands the inner workings)

    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 found here. I did not get a strap with a little blue plastic pendant at the bottom, I ordered two: one with a purple star and one with a big orange cross. They should have mentioned that there are different variations available, but this is more DX’ fault. Last point, the strap is a little bit expensive.

    Other: A strap with cute beads that can change from colour. Will look good when attached to your belongings. A little bit expensive, but worth it.
