Why are your sets so cheap compared to Lego - are they poor quality?

Put it this way, we are big Lego fans in our house - our sons have bucketloads of the stuff. When we bought our first Cobi set (the Sherman Firefly) in 2016, we were so impressed by the high quality bricks, design and relatively low price (compared to Lego) that we decided to become a Cobi retailer! The vast majority of our customers are equally impressed with the quality and value for money each set provides.
