I'm not sure about that, but to be on the safe side you can ask friends and family. Ideally, you can send out your product to influencers for free as I said to receive their feedback. But, I don't know if you have a budget for that, so the first option is also good. No matter what anyone says testimonials are important (not saying that is the only factor why it's not converting). How many times do you go on a website and purchase something without reading reviews first? I almost NEVER DO.
But I would advise that the reviews should sound genuine and highlight the (real) positive aspects of your product. Otherwise people will buy, be disappointed and never return again.
