Used this product to cover an area under my screened in porch upon which to park my convertible in the winter. No significant leveling involved, snaps together like a charm, and durable/sturdy as the day is long after you fill it with pea gravel...works wonderfully. Will buy again and am looking for other projects to use this product. Fantastic solution if you don’t want the trouble and expense of paving or otherwise installing a permanent solution. You could move this later if you decided to use it somewhere else, and I suspect it’s useable life is quite long...seems very durable.
