How many times do you test a toy?

So far, I've only reviewed products that I've used at least 10 times. I really like to know what I'm talking about before I start talking.

There are a couple of toys I've gotten that I haven't been able to use properly, e.g., the Tantus Severin Medium]; I'm going to try it at least a couple more times before I throw in the towel. I may just set it aside, possibly for months, until I reach a higher experience level.

I started to write my most recent review, of the Fleshlight Flight, after using it only twice, but I'm glad I waited a couple of weeks. I figured out some things (how much lube to use, how to clean it quicker...) that made it a much better review.

I use them for at least 8-12 hours, obviously not all at once. I will try them out in one night but the ones I do not like I really try harder to get something good or an alternative use. I end up putting more time into them to figure out new used.
