Help! £50 budget – which one?!

Hi all, I’m sure this has been asked a thousand times but I’m getting myself lost and struggling to make a decision!

I am looking to buy my first prostate massager, I’m not new to anal play and I’m lucky that my wife pegs me and I use a selection of dildos and plugs, but prostate massage is new to me!

There are several that seem to fall within what I’m looking to spend and all have very positive but also negative reviews, I also appreciate this will be down to personal preference. It seems my choices are…

Aneros progasm junior £40
Aneros progasm ice £45
Aneros helix syn trident silicone £50

Would love some help and guidance! Thanks in advance for your prostate wisdom!
