I’m sadly a little. This is what I get to know till this moment and my minds about this.
TLTR:
Sunlu S2 - not perfect but not trash at all. It dry your filament. Temperature and humidity sensor appear to not work properly. Most reviews uses old revision and they not reviews Sunlu S2 with fan (new revision) so them ratings was not very good.
Bambu Lab packs not very well for 5%RH - 15%RH. They are not absorb so much humidity. If you use Bambu Lab packs only you see 30%RH - 45%RH. BUT if you have high environment humidity (60%RH - 100%RH) you are unlikely to get the AMS down to 5%RH - 10%RH even with AMS Dry System. More likely you will have humidity of AMS about 15-25%.

Summery:
My Sunlu dry not bad but get incorrect %RH and temp.So I get wrong data about temperature and humidity. I put in dryer my hygrometer it show 20% (this minimum %RH of my hygrometer) and 49C, at this time dryer show me 36%RH, 55C and filament has dried more 10 hour.
I need AMS Dry System.
So I think my the problem isn’t with the Bambu filament baceuse I used it right after 24 hours drying and it was most likely dry. Now I have scale and I will check it.
The search for the problem continues…
