I started with one of those for at least a decade and upgraded to a large dispenser jug in the fridge for like 4 years. The small pitcher doesn’t hold enough water needing a refill pretty much every use (large water bottles, and several family members). Refilling means setting it in the sink, add water, wait long enough for it to filter the first batch, then add more and return it to the fridge. Takes too long. The large dispenser jug was a PITA to take out, filter water into (using the top of the Brita pitcher in like 5 batches), then return to the fridge around twice a week, if not more. It’s heavy, that process takes a while, and you’ve gotta babysit it to add enough water and put it away to be chilled. The countertop cooler filter is much more convenient. It holds ~5 gallons of filtered water and you can dump like 3.5-4 gallons into the top at a time. Takes like 1/5th the time to refill with no babysitting/waiting around to add more water. The major upgrade there is the hot filteted water. It is SO nice being able to get boiling hot filtered water immediately. I really like hot chocolate, my sister drinks a ton of tea, and we all like instant cup-a-noodles. Never wait for a kettle, and cleaner water than the kettle.
