Questions about Braun Silk Expert Pro 5 PL5140

Does it come with a 2+2 year Swiss guarantee? The available options in stores have a four-year guarantee.

To be honest, I'm completely confused by the offers here for Braun Silk Expert Pro 5: There is this offer here for a device that is suitable for the "bikini zone", among other things - since it is a device for men and women, I assume that this also applies to men in a figurative sense. But then there is also an offer for a "Braun Silk Expert Pro 5" (without "PL5140") -> https://www.galaxus.ch/de/s6/product/braun-silk-expert-pro-5-ipl-geraet-18526701 It doesn't say anything about "bikini zone", but it does advertise "100-day risk-free trial." That sounds good for a technology that I don't quite trust yet. But it doesn't say anything else about exactly how it's regulated - just this one sentence. However, the device will only be of any use to me if it is also suitable for the bikini line or the male counterpart. Are there various devices on sale here under the name "Braun Silk Expert Pro 5" (some with, some without additional letters), some of which are only suitable for the intimate area, while others have a right of return? And what would such a 100-day right of return look like? Or is it basically always the same offer, but for some reason different focus was placed on the product pages here? I would be grateful to the BRAUN experts here if they could shed some light on this. Thank you very much!
