Hi,
Seems to be an OEM made by the biggest asian manufacturer....
The pen is exactly the same one as SAIKE or HAKKO.
The tips are very cheap and you can get them easy on Ebay for around 1.95 $ free shipment.
You can also find the heating element (ceramic) for less tha 10$
Extra iron for around 12$
So no worries, this is a good plan....
Personnally i got a SAIKE 852 D+ 2 in 1 (iron+air), with tips for 88.99$ and the iron is perfect ...
On top of that : ESD Safe...
So for your price 46.95$, this is a good price...
Hope this helps...
Cheers, Henri
