top stirrers ?? seems like a good idea for 200-500g extracts

my buddy got the the big Prime A day sale. he was stocked due to the fact no more picking up 3L or 5L beakers and flipping them end over end. has anyone had experience with a top mount stirrer. i think it might work easier get the whirlpool going instead of trying to spin a stir bar threw a thick layer of sla mixture of bark and solution? would love to hear what anyone and every one has to say. only down side he told me there’s no ptfe covered rod there’s a SS rod. can you use SS? it’s made by vevor. buddy thought it came with a ptfe covered rod

Apart from the rod not being a suitable material, another thing that would be a concern of mine is splashing of concentrated basic solution out of the beaker during the stirring. If your buddy comes up with some kind of lid to put on the thing while it's stirring that would be great.
