La forza aspirante non è eccessiva, ma devo dire che per un sistema di irrigazione interno per piccole piante fanno il loro dovere. I cavi però sono molto fragili

Avevo cercato di utilizzarli ma con scarsissimi risultati.

1st the product specification for this has obvious errors. At the top of the page the working life is quoted as "The use of working life of around 200 hours ". But lower in the full details it is "Continuous working life of 800 hours". So which is it? 200 hrs or 800?2nd - see picture of pipe supplied. This is all kinked and pinched as it has been poorly wound prior to packaging. So yes you get some free pipe but its pretty much ruined already.3rd: Lift: the lift is quoted as "Maximum lift: 40-110cm". Which is odd. why would it need a minimum figure unless it is because inconsistencies in the manufacture mean that some have a lift of only 40cm and others 1.1m??? Well, I Measured 1.1m of pipe and tested all 4 'pumps' and marked the max height reached by each one. From my testing only ONE of the four pumps managed 1.1m and then only just. (For the test these were powered off a Thandar Bench PSU capable of supplying 5V at up to 7A)During testing all four pumps drew around 30mA no more. The Spec says "Working current: 130-220mA"One of the 4 pumps was very noisy and clearly has a unbalanced impeller and is useless for any quiet operation ie as advertised. it would drive the fish nuts if i put that vibrating thing in my fish tank!!The short cable adds inconvenience meaning that for practically any use i can think of, the lead needs extending with a submersible waterproof junction.These are only of any use as i have plans other than the advertised function for them.
