USB Nano Pump Lifespan?

[demicent]

How long have your USB Nano Pumps lasted?

I bought 2 originally and had 1 fail after 5 months or so. I purchased 2 more however. 1 to replace the failed one and another backup. The other original I bought is still running strong.

I've had 2 or 3 out of about 6 die between 2-5 months.  The rest are fine (6 months).

Thanks for the replies.  I've had one dead on arrival, and two others die within 3-6 months.  Out of about 23 I've purchased.  I've taken apart a dead one to see what's inside!  Interesting.  I tried buying one from Amazon, but the funny thing is that the part where you push on the air hose is slightly narrower, so occasionally the air pressure causes the hose to pop off!  Some of the newer surge protectors that I've purchased have USB outlets, so I'm plugging a couple in directly to that without the provided adapter, to see how they go.  Seems OK so far.  Hope I'm not going to set the house on fire.

I have three, one died on me very quickly within the first year but the other two are going strong. Strangely the one on the 5 gallon is the one that died, the ones on my 270 gallon going strong, I think I got them last juneish
