I've use Fiverr many many many times and I see their is a problem. If you do get a poor job back the vendors at fiverr, they will beg you not to give them a bad rating. So I leave a good rating because for what I paid how can I not. Wish Fiverr would put a stop to their vendor base begging for 5 star reviews which makes us feel awkward. I also have had many very good projects completed with fiverr vendors. I give it over all a thumbs up.
