It's likely too big to use as MLT for 5gal batches, since the grain bed would only be a few inches thick. Another concern for boils is the high surface area to volume ratio, which means extra fast evaporation rates. Just a concern though, since you could accommodate with extra wort.
I messaged the seller asking for pics of the strainer and lid if it's included. Just want to make sure the OP didn't just get lucky
