O-like is a good seller.
I got my modules and an IR dilda from Susie without problems, paying with Paypal.
You can ask her to remove the stickers with the indication of the power, and maybe declare them as <5mW in the documents, if for custom problems ..... or also (but you have to ask her if is a feasable thing, or if this cause them too much problems), you can ask her if is possible to send them marked as "spare parts", and have the modules sent in one package, and the bodies (battery holders) sent in the other package with the batteries ..... this way, being not complete pointers, maybe the custom offices can say nothing (but i repeat, better ask her first)
The only bad thing, for me, was the delivery time, but as i already stated,
that was NOT Susie guilty , this here happens with any package ..... i'm in Italy, and here custom offices always stop items from outside to here, especially if coming from china,
for usually 15 to 30 days in deposit, with no reasons at all ..... they don't keep them blocked for law reasons or for something specific, they just left your items sit in the deposit til someone wake up with nothing better to do, and decide to check some of them ..... bah
