I purchased a new SCV50 compressor, which didn't work from the start. On ispection, the air outket elbow from one of the two compressor was split and the plastic cover was damaged. The company didn't want to replace it and I wasn't prepared to repair a brand new item. Their customer service department appears to be made up of young with no engineering ability whatsoever, so after two months I was eventually refunded the full amount under the terms of the Consumer Rights Act 2015, as the unit was less than 30 days old when I complained. In fact I complained on day two of ownership. These compressors are made in China, not the UK. They are NOT tested by SGS and identical units can be purchased elsewhere in places like Machine Mart. Look at the Google reviews of this company, in particular concerning air compressors and you'll see numerous people all complaining obout the quality of the compressors and failure of SGS Engineering to deal with the complaints. I would strongly advise potential customers not to not buy anything from this company. Look at the number of SGS compressors on Ebay, going cheap because they are rubbish....... used just three times because the forth time they don't work !! I got my money back by going via my credit card company and a Section 75 and the help of the Trading Standards and Citizens Advice, who incidently, were brilliant.
