I like how you can use it as if its an in house team of workers! You don't have people at your office all day working away but instead they are out there earning money online or even doing jobs around their home town which is awesome because then when we need them again just ask them back!! It's very easy once set up correctly so no problems with me using amazon mechanical turks services. Nothing really bad about anything i've come across yet other than maybe having more options would be nice? But not too much hassle either way though! Its great being able to get extra hands whenever needed without paying high wages through my own employees who may feel underpaid themselves due to overtime etc.
