Hi, I was very interested in what Issviva said their device had to offer on their website.
However I’ve since looked at the Trustpilot reviews, and it’s not got many happy customers.
Have you any experience of Issviva, as their device is not cheap, but if it did deliver all that it promises, I’d consider that expense.
if you know of any other company yhat produces a similar device, that has got good reviews on Trust pilot, then it’d be interested in hearing your experience.
Thank you so much
