Bought this one as a back up. Running 2 already for 6+ months with no problems so far

Produto de qualidade.

The pump arrived on the estimated date. The operation is quiet, but in high speed it can create some noise. Due to my tank dimensions a power adapter was needed in order to decrease the input to 15 volts

wave maker is nice and compact and packs a punch, have only had it running for 3 weeks now, so cant comment on reliability, but very happy for the price.

Silent, powerful and cheap ! what else ?
