I don't know the company you mention from the directory, but if you have sourced them from there they will have been confirmed as a legit supplier, meaning they are not going to scam you.
Just bare in mind that although SaleHoo performs quite in-depth checks on all suppliers requesting entry into the directory, to ensure they are safe to deal with, it can never be with a 100% guarantee.
That's a guarantee that no one will be able to provide, quite simply because no one can see what the future holds, but as of this time they are confirmed as a safe supplier.
Now what does safe mean?
Well there is usually some confusion around this point, so just to clarify. Safe means from scamming you, it doesn't mean that you will be able to buy legit branded products from them, and if they are a Chinese company based on the Main Land, then you will definitely not be able to source genuine branded products from them at all.
So just bare all that in mind if deciding to deal with them :)
