Overall, very good product. There is a learning curve when assembling them and bending the flat corners to 45 degrees, you can't go to 46 degrees or they will snap very easily. I lost about 10 out of the total order due to the plastic cracking at the corners. But, once you figure out how gentle you have to be, then they work and display great!! Shipping is shipping, I blame UPS or FedEx for delays not EcoTek. Once you remove the protective film, they are crystal clear for optimal display of signed items.
