Question about Sage BBQ & Press

We have used this grill innumerable times. Mainly for making toasties / Panini - but also for grilling meat (steaks), chicken, and burgers. The grill surface is 100% fine. My only gripe is that it would be better if the plates were thicker (cast iron) so that they don't cool down too much when you put meat etc on them. Don't over fill if you are grilling... do smaller pieces at a time eg. 2 burgers even though there is room for 4. I use the grill to toast the burger buns first before grilling the meat. Works a treat.
