Are snuffle mats ACTUALLY good for dogs?

I got my baby (12 week Alaskan Klee Kai) a snuffle mat today because I’ve heard really good things about how they can tire your dog out while providing healthy mental stimulation, he goes at it for maybe 5 minutes but then gives up though there are many treats left. Redirecting works a bit but he eventually loses interest again. My boyfriend then said “It’s probably one of those things that say it’s good for dogs but in reality is frustrating for them because all he wants to do is eat.” This got me thinking if he’s right and this is just a marketing strategy that targets pet parents. What do you guys think?
