Has anyone used plusOne vibrating dilators?

Hi all,

I'm 8 years into my vaginismus journey and just want to get to the largest dilator.

I can comfortably use the 4th CalExotics dialator but the jump between 4th to 5th has been too hard to bridge so far. Specifically, I'm struggling with the diameter increase. It's also a mental block because of the pain / thought of failure.

To solve this, I really wanted to buy a dialator that was inbetween size 4 and 5, and that vibrates to help me relax the muscles.

I came across these: https://myplusone.com/products/plusone-vaginal-dilator-set-6774 and was wondering if anyone here has found them good? The biggest size is about the same size as my size 4 dialator, but it does vibrate.

They are pretty expensive here in the UK (£75) so I wanted to check here before I commit :)

FYI - I haven't been able to find a regular vibrator that is small enough, which is why I'm looking at plusOne
