The simple fact that you start a thread and ask for feedback, including negative feedback
That kind of says it all.
A lot of websites publish reviews, but only ever the good ones and some I’m sure even write their own.
There are already dedicated threads here in the forum to show the quality of service
etc.
Dotted throughout the forum are people that have had issues with orders and implants, EVERY SINGLE TIME, it is rectified.
(@zwaks post above as a prime example)
Personally I have never had an issue with an order from Dangerous Things, although I actually want to experience that…
I see people mention “I accidentally got sent X instead of Y , DT immediately sorted me out and sent me my X and told me to keep the Y for FREE”
I want free stuff too!!! 
I look forward to seeing more examples below, even though I know I will be envious…
I’m sure a review section on the DT webstore would be full of great examples, but it would likely get spammed with comments from conspiracy theorists and religious nut jobs.
