Received this item in early May 2020. We have had a very cool and rainy spring with very few days over 78. However, even in this weather the box lid has begun to warp and lift, (yes, it does sit in full sun but really that should not be an issue when something costs $200, and again, it hasn't even begun to be hot here) Now the box lid does not lay flat in June, 2020. Totally unacceptable. Of course, the warping has begun after the 30-day return policy expires, and now I sit on Hold with Customer Service listening to elevator music, for "possibly more than 45 minutes," as the recording keeps saying. There is no option to lodge a complaint another way, other than via phone. Total baloney.  Would not recommend this purchase.
