Useful features included being able to select the size of the foam and lots of different types of foam with description. The descriptions are useful - presumably there will be a lot of amateurs such as myself and the hints and tips help me not make a silly mistake. Most features work well Things that could be improved - the home page is sometimes slow in loading, resizing a piece is difficult (you must add a whole new piece) and editing is difficult (when you click on an item in the basket to change the foam type and save, a whole new item is added to the basket rather than editing the original). I experienced an error when making the first card payment but instead of a friendly error page it showed a non user friendly page (this would suggest the error handling needs improving in the code) Though overall I am pleased - thank you :)
