I normally stay away from any product that has double additives in there name , and especially when one of them have meaningless terms as one of them [ gold ] .
The offer has a couple of things going for it , its in your country and 15.00 is not bad ?
Just did a quick Goggle on it and prices were more than halved depending - that usually an indicator , then one of the top replies was an EEVblog post talking about it as a Hakko clone .
Enough of that , not sure if you can find , I do a lot of shopping in eBay , and the more it costs the longer I will look , because given long enough almost anything will be sold over time for a term I learned going to auctions , sleeper , for any number of reasons an item is not seen / bid on or noticed and goes real cheap .
I have a bunch of high end professional soldering gear that most came from eBay , maybe the best deal and JBC Micro desoldering station , this was new in box's with replacement parts - 5 each of 3 different tips , filters , power supply vacuum pump complete , these retail for $1500 to $1700 , I got it for $420 including shipping .
Then a NIB JBC single soldering station for $225 , and a whole bunch of Metcal stuff real cheap used 3 of the SST models off craigs list $30 for a box of all kinds of soldering stuff , including the Metcal , then one of the Metcal desolder guns , tweezers , and then someone that had about 80 tips of about 15 types all new in packages .
And other stuff , the point is get to know the gear , especially the beast gear , then keep an eye out for the sales that most everyone else missed , so you are not competing .
It could be an issue with sourcing on either side of the POND
Shipping is getting way over priced .
Here is one that is a good started and on sale sometimes
