As a decorative item it might be worth 4-4.5 stars but as a functional jug I think 3 stars are generous. Overall, the quality of the materials is poor and the price is high. I think 10-20 euros is a reasonable price with its value being around 10.
The main negative features are the very slow flow and the non-removable jug. Especially the non-removable jug makes it impossible to add any other object to help with cooling besides ice (e.g. metal balls, etc.) while also making washing a frustrating process.

In conclusion, it is more useful to fill it with some colorful liquid like soap and leave it aside for decoration rather than using it often.

As several have mentioned, it mainly serves as a decorative piece, as the functional part is almost non-existent. Beautiful for decoration (placed in Gameroom) but it should be sold with this property. Literally filling even a glass with any liquid through this specific product is a feat! This is my objection which justifies the 3 stars - very beautiful decorative, definitely not a Dispenser.

Don't expect it to run like a faucet, but for fun or decoration, it's very good. The bucket is not detachable.

For effects and decoration, it's just what you need. It works with both tea and apple juice to troll people. It's not for functional purposes
