I haven't used either, but the Summit one is just a private label cooler that anyone can buy in bulk with their name on them. It's available all over Amazon under different names / sizes:

https://www.amazon.com/Electric-Portable-Freezer-Compressor-vz-cf55LG/dp/B08V8VFF35/

https://www.amazon.com/Refrigerator-55Liter-120-240V-Portable-refrigerator/dp/B08NCZF438

You could use reviews on those to determine how comfortable you are with the brand, and then buy the least expensive one if you want it.
