“Strap-On-Me” double density dildo advice needed

Hey folks!
My girlfriend (23f) and I (23f) are trying to step up our strap-on game. We aren’t new to this but wanted to take the next step so we have been thinking about getting a double-density [dildo]( by the brand “Strap-On-Me”.
My gf is a bit concerned that it may be too soft, as one of the pictures on the websites shows it being quite flexible. Don’t get me wrong, we’re looking for something comfortable and enjoyable but are a little worried that those are too soft for penetration.
My gf has only been with men before and said she wouldn’t want it to feel like a semi-hard dick so I’m really trying to avoid that.
Does anyone have any experience with this dildo? Was it too soft/bendable or just a more realistic feeling than with a single-density silicone dildo?
