I used Made by Cooper for a run of 500 badges. The design originally included some small cutouts which they warned me were too small to manufacture, saying the minimum hole size for the cutter is 2mm. We increased the size of the badge to accommodate the minimum cutout size. The final visual we agreed on showed these cutouts on the front and rear of the design, with a minimum diameter of 2mm. The badges came through with tiny, tiny holes (< 0.5mm), much smaller than the size we agreed. To be specific, the cutout started at 2mm on the front and then narrowed to 0.5mm at the back. The result wasn't great and if I had been warned about this I would have changed the design radically. I've had to apologise to my customers and accept a few returns. Unfortunately, I don't believe Made by Cooper can be relied on to sufficiently inform their customers of manufacturer limitations. They will respond to this review saying something like "they were made correctly to the tolerances" or asserting that the badge "has been made correctly" as they repeated multiple times during the email thread in which I tried to communicate the issue and perhaps have them update their guidance appropriately. They have yet to tell me *why* they believe my problems to be invalid. Ultimately you go to Made by Cooper instead of directly to the manufacturer to get their experienced design step - they have made many badges and are supposed to know what works and what doesn't. I think they failed in their fundamental job as the middleman between me and Alibaba. I think the badges themselves are of reasonable quality, their website is simple to use and their design team responded quickly. However, without the ability to own up to their mistakes or even present a basic case for why it was actually my fault (which I would gladly accept if shown a line or instruction I somehow missed) I couldn't possibly recommend them to anyone for anything other than an extremely simple design.
