The xtr plate works very well, the flex on it could be more, but it's understandable due to its thickness. The plate itself is durable and easy to clean, and can hold big projects easily (printed a red ancient dragon from mz4250's patreon), the flex itself does not *pop* parts off consistently, but taking a Spatula to the print whilst flexing it will have them slide off instantly, all in all, the kit is a success, although as a reminder, remember to put the spacer on if you need it.
