Do not waste your money. The solution delivered did not meet the criteria and was of a poor quality. The rework was then delivered after the due date. When the poor quality was raised the expert argued that it was of a high standard despite clearly demonstrating that the work was not used and missed several key elements required with the rubric. The money back gaurentee is a lie. I have been refused a refund even though the solution was not used. Very rude after service. Very dissatisfied and would definitely not recommend that you waste your time or money! STAY AWAY! I would give no stars if I could.
