So it's been a while since I've used Kaspersky, and i was wondering how their licensing work, especially regarding activation/deactivation when reformatting the PC/phone or changing device ?

Does Kaspersky works like ESET, Norton or Emsisoft where we can manage license activation directly online with virtually no activation limit, or is it like Gdata or HitmanPro where there is no way of managing or deactivating the product, and once activated it counts as 1 license used ?

I'm asking as I'm thinking about purchasing Kaspersky Total Security, but I'm worried i might encounter problems as I tend to reformat my computer a lot and change my smartphone several times a year. So purchasing a 10 devices 2 years license would mean I'd reformat/change device a lot (30, 40... maybe even 50 times) ?

Does anyone here have experience regarding Kaspersky and if their licensing works well for people who reformat a lot ?

Thanks a lot

If you buy your license in Kaspersky website and you add it to mykaspersky portal you can disable the license on every device the times you want as Emsisoft, but I have not tried doing more than 5 activations on the same day (3 devices license here)

In order to avoid activation issues after reinstalling Windows, you need to have an officially purchased license, not one from ebay etc. If you use an ebay licence, and you reformat your hard disk, you might not be able to activate. It's unpredictable exactly how many activations an ebay license will give you.
