bought twice and each tube had atleast 1/2 that didn’t light up. mine didn’t come with the aqua blue color in pic. but amazon customer service did work on the issue and fixed the glow stick issue.
connectors: the connectors supplied are hard to use compared to those supplied with competitor's products. you will spend a lot of time working the ends into these connectors. they do seem pretty secure when finally in place. i doubt that children would have the patience to successfully complete a bracelet.length: the nominal 8 inch tubes are slightly shorter than 8 inches, and noticeably shorter than those from a competitor.brightness: other than the green tubes, light output is somewhat low. the green tube will outshine tubes of other colors.
bought these for use at disney world. approximately 1 in 6 lit up at all, and even then they were very uneven and dim. used within a few days or receipt, so age should not have been an issue. i cracked them every which way and shook them after cracking with no improvement in results.
good thing we didn't have a lot of trick-or-treaters this year. i got about half the green yellow sticks lit up after breaking the inner seal in about 5-10 places (usually it only takes me one or 2 times). most of the others were pretty old and half-dried up. the connectors were cheap but seemed to do the job once you get the hang of it.
compared to other glow sticks that were used at the party, these didn't seem as bright as the others. they start to lose its glow after an hour or two. the quality didn't seem all that great. they're good maybe for kid events.
i bought these to hand out for halloween to the neighborhood kids. upon trying to assemble them i noticed that the connector would not hold the end pieces together. i would make a bracelet and it would quickly slip apart.as far as the brightness of the pieces it started out fine. it within 10 minutes the brightness faded quickly and they became very dim. i stopped handing them out early in the evening.
they do not light up bright and when you try to bend them, they leak they spring leaks, and the adapters do not connect properly terrible product i would never recommend, and i save them for halloween and lost my return by a few days
these things are garbage, they are not bright at all and only stayed lit for maybe two hours, but who cares anyway you could barely tell they were working.
old/expired not bright very dull defective item. not happy with this item do not recommend very dull not bright at all and half of them didn’t work. do not buy
