I like to test the toys a number of times before writing a review... At the very least, five times, and on separate days because there are lots of factors that affect usage and response.
Even though I have a lot of free time, I don't always feel up to using toys (or doing anything sexual in nature). As a result, it takes me more than two weeks after receiving a product to write the review. I had already used a number of products when I had joined, so I had plenty of review material.
Luckily for me, I've finished testing my last purchases, and a new one is arriving pretty soon.
