Before finalising a purchase, it is worth asking a supplier a short list of direct questions: what surface material is actually being used, what warranty applies specifically to writing and erasing performance, and what installation support is included in the quoted price for a large dry erase board. It is also worth asking how the board is expected to perform after several years of daily use, rather than judging purely from how it looks and writes on day one. A supplier confident in their product should answer these questions clearly and specifically, rather than deflecting to general marketing claims. Getting these answers in writing, alongside the final quote, gives a clear reference point if any question arises after installation. This small amount of due diligence upfront is far cheaper than discovering a mismatch after the board has already been installed and put into daily use.
