The sex toy, created by Tracy's Dog, was a hit with the mum - and her lengthy review led to a stampede to buy the product, which has an 83 per cent five-star rating on Amazon.

She started off her post detailing her scepticism of the sex toy, saying she expected it to be average after being recommended the product by friends.

"Having read everyone's reviews, I had high expectations, but with the price being under 50 dollars, I wasn't exactly going to be shocked if it was mediocre," she wrote.

"A few friends of mine bought it recently and told me of its power. I was warned to take the day off, hydrate and above all do some stretches. I thought they were being such drama queens."

After being impressed with the discreet packaging and quick charge time, the woman was soon so impressed with the device that she had "blacked out", saying that her legs "went straight out like those goats who faint when scared".

The graphic review explained how she played with the settings to have multiple orgasms, to the extent that she actually injured her hip and back. She added: "I shook for a good 5 minutes, i couldn't get up off the bed if even wanted to. I stared at my ceiling dazed trying to remember who i am and what year is this."

The viral review concluded by thoroughly recommending the product. The reviewer wrote: "So in conclusion, this met and exceeded expectations. Hydrate, make sure you don't have to do anything that involves decisions or brainpower for the rest of the day. And for the love of god, stretch like you are about to run the 500 meter dash".

On Twitter, fellow Amazon users were loving the review, calling it "pure gold".

People even said the reviewer should work in advertising, posting screenshots of their orders going through and saying they'd bought the product just because of her descriptions, even though the rush to buy the product had resulted in the price increasing.

Reviews just don't get more honest than this.
