1. Check their "contact" or "support" area. Is there phone number and physical address there? If yes, give them a call first to learn about the products.
2. Look at their front page, is there any live support available? If yes, go ahead to chat with them for a while.
#1 and #2 ensure you to deal with real companies. You can get quick refund if you do not like the products.
3. If you cannot find any phone number or live support button, go ahead to send them an email to ask about the details for the products. Wait for their response.
