Easy connection (after removing the original adapter)
Works perfectly
The notice specifies 4 w is 200 l / h, which does not mean much
60 cm pressure is more explicit (usually divide by 2 in real life)
=> In practice my fountain is 30 cm high, and the setting should be set to maximum for correct jets)
IN CONCLUSION:
5 stars because the service is related to the ridiculous asking price including shipping
remains to be held in time ...
