Forget it Time Owned: more than 12 months.
I have bought this from a German shop years ago for under 100 euros and all i have to say that it's not worth its price...
1) at home: too noisy fans, worse than my 800W PA!
2) portable: i was on a vacation in an RV and the antenna was outside on the car, 30 feet coax in to the RV to operate from there: the thing was sensitive to the 40m band (20m OK).
3) birdies: an other reviewer mentioned them, i did not realize any issue like this, but maybe there actually are birdies.
To sum up: noisy fans, sensitive to RF under 10mhz (my guess). Otherwise it works.
If you're on a budget and in Europe, i recommend the purchase of a Microset they seem to be more serious and more suited to amateur use (i am satisfied with my 50A Microset PS).
I definitely do not recommend this product!
I'll try to sell it (mentioning its issues), as i want to get rid of it...

Lots of birdies!!! Time Owned: 0 to 3 months.
I bought it as a second PS but this was not suitable for HF: lots of birdies all over up to 6m!!! Besides that, the fan was too noisy for me so I had to remove it with no problem with it. Now I use it for my VHF/UHF rig and other devices that need 13,8V. That was my first swithing power supply and propably the LAST ONE...73'S

Not for HF Time Owned: 0 to 3 months.
I've purchased 2 of them today, pricing was nice and the size as well. No issues on VHF and UHF, but the power-supply creates massive RF up to 10 MHz. Looking at the data-sheet from the supplier sais everything: 100mV ripple from DC up to 10 MHz. With a basic load of 2 Amps both supplies create of noise-floor of S9 from 1810 to 1950 kHz, making the usage of 160mtrs impossible.

I would only recommend this budget SPS for Hams don't want to use HF.
