Hello,
There are positive and negative ones. Some of the negative ones are because of payment problems. People do not follow payment instructions then blame us. They should never send payments online. Some of them because of post service delays which is not in our hand, they are impatient and do not wait long enough we never let our customers down we always reship undelivered or lost orders.
And most of the remaining negative reviews are simply fake made by rivals. Our company is in the business more than 10 years having thousands of loyal customers which makes us a target for some bad rivals.
We are offcial seller of GEnSHi labs you can check us at their page http://www.genshilabs.com/supplier-check.html

Thank you.
