I just recieved one of these UV13 units.
From what I've read here just now, they have improved in quality quite a bit.
I havent yet had the chance to connect mine to water, but the threads in the main body of the housing are now a single piece, And are threaded into the body itself.... they are not inserts of any kind.
also the blue connectors that screw into the main body have a nice oring on them, which allows a good snug, and seemingly water tight fit without the worry of cracking anything.... i had them nice and snug, screwed in far enough that the oring was no longer visible.
The adapter of this unit is custom built.
you can tell by looking at it, that the LED was drilled by hand, and the transformer is much mich to light to be a core and coil step down.
Instead this unit uses an electronic step down circuit.
I havent disassembled the transformer, but its a good guess that the guy selling these on ebay got them at a steep discount because they didnt have transformers or something similar, and he managed to get a deal on electronic step down transformers, and had the transformers for the sterilizers custom made, or built them himself with custom parts..... which is why these units are so deeply discounted.
Also make note of the "LifeTech" stickers that replace some of the Jebo logos (on mine at least)
Having searched google previous to buying this, I remeber seeing actual Jebo models H13 as being 18W instead of 13.
So as you can see, these are Jebo sterilizers, but they have been modified by the person selling them on ebay.
at the very least..... the box is still Jebo
