In addition to the EOS upgraded I still have the successor Olight I3S who not chirps, but has an equally cold / bluish light.
The Ti3 neutral white (warm color temperature) I am very satisfied.
The knurling (roughened surfaces for turning) is much better / more pronounced, which is also necessary, as the thread a little harder (not meant to be derogatory!) Runs.
Color temperature (in the warm white):
Not the "greenish", rather the "brownish / orange", what I really like.
In addition to the color temperature I like compared to the Olights that the scattering angle is twice as large.
If you are looking for something with the Olights from normal distance, for example in a closet, the lamp scatters far too low and there is a bright little spot that acts outshone. When Ti3 has a much larger and more uniform dispersion.
Also seems to me the Ti3 ago brighter than my predecessors.
Considering that the Ti3 is 40% cheaper than my I3S, I would personally the price / performance ratio ago no longer think about what to order ....
Only the key chain affects me personally, unfortunately, as the cheapest that could only be found ....
But since even with my I3S not much better this was (only in old chirping iTP A3 EOS Upgraded was much better) you have to probably come to terms with that one because same time must look for a good substitute itself! ;-)
I'd like to pay from the outset two euros more (for a decent Carbine with chain, would the manufacturers do not cost 50 cents more at high volume than the current chain) so as to have at least one snap hook as in the A3 EOS upgraded instead later retrieve that and having to order a 5 Euro Carbine with additional postage ....
