Every time received goods within a few days and the parcel is always in good packing condition. The components are in vacuum sealed packing. And the parts work fine. That's awesome!

We get the goods with original packing and label, the Date code is new and the delivery is fast. That's awesome. There is no doubt I will buy more parts from this web.

As an electronic engineer we do face the problem that when we design the product and found some item is obsolete, luckily we found this supplier and they can supply most of obsolete parts. I would say they are really helpful for us .

At the beginning, I learned about OMO on Alibaba. For convenience, I placed orders directly on their website, and the goods would arrive at the fastest speed.

Delivery two months .. I haven't checked yet. If anything, sign off...

Ok

It was very long before rostov, 62 days, the track is untraceable. In general, november 10 a lot of what i ordered, all tracked long ago came, a pair of untracked, including this parcel, came only a couple of days ago. About the board itself: the appearance is assembled well, on the back side are noticeable barely traces of soldering, the adjustment of current and voltage work like the converter itself. Of the drawbacks-for example, the input voltage of 12 v with a current of 1a (stable and tested), the output set a limit above 2a and 5 v idle. With a load of only 300-400ma, the output voltage drops from 5 volts to 3.1 volts. Perhaps i got a strong rejection, or maybe they are all such, in any case i do not advise, if you are interested in a stable output voltage at dynamic loads. For small currents there are alternatives and better.

Resistance from 420 kohm to 460 kohm
