One works to such an incredibly low standard that there is no way we could possibly work with them. See here for a lot more information about this. We used to supply another two until it (quickly) became apparent that they were only buying products to try to copy them. One of them even used to market their work as being a copy of ours. This is clear if you look at some of them - clearly direct copies of our designs, some of which they try to sell for more money than our originals, with far less parts. Some 'specialists' couldn't come up with anything original if they tried. Everything we make we design from scratch, with virtually no influence from what anyone else makes. Copying the work of others is of no interest to us - just doing the job right.
