Does Banana Loca actually keep things mess-free like the packaging claims?
Not really. Banana Loca advertises no mess and easy cleaning with the included bristle brush, and with a thin spread a rinse can be enough. With sticky fillings like Nutella, peanut butter or honey, though, you will need to take the gadget apart, brush out the channel and nozzle, and reassemble it, and it does not store neatly afterwards. If mess-free cleanup is your main reason for buying, treat that claim skeptically.
Will it work with any banana, or does size matter?
Size matters. The corer needs to pass cleanly through the middle of the fruit, so a banana that is too small or thin can split, and one that is too big may not fit the holder, in which case cutting it in half and filling each piece works. A medium, fairly straight, just-ripe banana gives the most reliable result.
Can I use it on anything besides bananas?
Yes, cucumbers work well. Core them and fill with flavored cream cheese or a sour cream or mayo-based dip, then slice into rounds. Banana Loca does not officially list other produce, and anything much firmer or wider than a cucumber is unlikely to fit or core cleanly, but for cucumbers it is a genuinely useful second trick.
Is this gadget worth the money?
Only if you will use it often. It is fun and it works, but it is expensive for a single-purpose plastic tool, and for occasional use many people will find that slicing a banana and spreading the topping on is nearly as good. If kids in the house will make filled bananas every week, the price is easier to justify.
Is it only for kids, or do adults use it too?
Banana Loca markets itself partly around back-to-school snacks and desserts for kids, and it is at its most fun as a family activity. But it works just as well for adults: a filled banana in its peel is an easy take-along snack for work or travel, and filled cucumbers make a savory appetizer. It depends on who will enjoy the process.
How durable is it with regular use?
Durability is one of its weaker points. It is an all-plastic tool, blade and handle included, weighing 14.9 ounces, and it is taken apart and reassembled for cleaning, so wear is to be expected over months of regular use. Banana Loca gives no guidance on lifespan. If you plan to use it daily, for school lunches for example, weigh that alongside the fun factor before buying.
