I've had two of these units and a Vauxhall 1.7dti fuel pump ecu in the last month off this company and will always use them in future. You can save your customers a fortune and still make a reasonable profit from the job plus You get e-mail progress reports and every job was completed and returned by date stated or sooner. They also give 7 days credit and a 2 year warranty which providing they don't vanish as a company is better than most main agent parts.
