Hi Copepod,
I've used my Tesino Pump for slightly less than a year, my 1 year warranty was a couple of days away from expiry, rather disappointing i must say.
Apparently, the manufacturer obsoleted Tesino pumps and i was given a Jebao DC pump in exchange. IMO the Jebao DC do come across as smaller, quieter than Tesino considering both have a similar output of 5000l/hr.
However, if i have the chance to choose again, i would have went for Water Blaster pumps, the fact that they stamp a 3 year warranty on their product signals a certain degree of quality and durability.
Hope it helps.
cheers
