Maybe this one actually works? Neither whistle nor switch worked on mine. At least I got a refund.
Would be much better without the whistle, it is size that counts in this market segment.
Whistle will be improved.
I have two of them with non-working whistle.
S for Silent
Sorry, no whistle 
How would that be different to the original, where the whistle was silent?
without whistle?
I hope that others are right and the “S” means that this one will be able to produce Sound!
I have one too. Pretty neat little light though the 200 lumen mode dies down fast. It’s nicely made though. The magnet is strong and the built in charging is great. If I were allowed two requests to make this little light better I would of course make the whistle actually work and I would make the magnet removable. If it weren’t for that magnet it would be in my pocket right now. As it is, I’m working on computers all day and have my smartphone with me at all times and computers and phones and such don’t really get along well with strong magnets. That said, the magnet did make it a nice emergency bathroom light when we lost power a few months ago. I used the magnet to hold it to the light fixture over my sink and ran it on medium for a couple hours before it needed to be recharged.
Oh wait…make it three things. Get rid of the cheesy chain! :confounded: It looks terrible! I wouldn’t put that around my neck if you paid me. :person_facepalming: A simple stainless chain would be much better. I would change that or just leave it out. An “antique-brass-look” chain isn’t going to appeal to many if any. Very cheap looking in comparison to a classy little light. If anyone disagrees please say so. Opinions vary of course and this is just mine.
I looked at the specs on the zanbase site and I don’t see anything different. What am I missing?
Smaller I hope.
Lots of wasted space in that light. I have Several AAA lights that are only slightly longer.
I do want the whistle on this light. It’s not that I need or want this functionality, but it gives the light such a unique design feature.
No brass whistle please. I don't enjoy the aftertaste of brass in my mouth.
Many people like the whistle, Me too.
These are currently on sale for $11.
I just ordered one as it looks pretty nice.
Sorry, I was saying the F6 is on sale. What is different about the F6S?
JasonWW,
You can hurry up and cancel your order.
The extras (whistle) that makes this light different do not actually work.
Why would I do that? I’m buying a light, not a whistle.
The whistle of F6S works all the time. It is much better than F6. Did you try it?
All the time I mean F6.
As I mentioned below, I bought 2 of them for a gift, but given the quality they did not reach their purpose. Now I do not need them either.
The problem is only in the whistle…
Can someone confirm F6S is better than F6? Can post some pictures for side by side comparison? Thanks.
Pictures won’t show if anything is better, just if they are different. You won’t know the S model is better until you blow on it.
Yes, i wish to see the difference that result in improvement on f6s.
Needs to be lighter. It is ridiculously heavy for its size.
( yes, I know it is brass- but feels like lead)
Brass is heavy, unless they use aluminum, else it won’t be light.
