These light up wands are OK. They're pretty short compared to others. The flashlight feature is actually pretty good. Strong flashlight. But the orange plastic is cheap and doesn't stay screwed on. If you bump them or anything they pop off kind of easily. The two modes of constant and strobe is good. And you can use these with a Rechargeable 3.7V battery which is great.

Ottimo prodotto! Ha 3 modalità,fissa molto luminoso,fissa poco luminoso e lampeggiante.Molto comodo per gestire il traffico o per segnalazione.. anche la torcia in sé fa molta luce e ha la ghiera che permette la regolazione del fascio luminoso

For ~$10 per light I don't think you can go wrong unless you maybe want a bigger orange cone (see picture for reference). I recently picked up a gig which will include traffic control. I haven't, as of yet used them officially but I have high hopes. Could Mag-light, Stream-light, or Surefire make a much higher quality unit at 5 to 10 times the cost? I'll bet they could, and for someone who is a bit snobbish about flashlights (I love my Surefires) I'd probably get one (because 1 would be all I could afford). p.s. I hate devices that require 3 batteries. I love that this includes a sleeve to allow for a single 18650 battery.
