Are these fake?

nd72, your first post a real zinger!! 😂

I would say 90% of anything coming off eBay or Amazon are suspect and should be avoided.

Where it really gets complicated is when the "real" product is manufactured in China (as most things these days are) . What can happen is the trademarked company hires a factory in China to manufacture a run of say 2000 of product X. The factory does a run of 5000 ships the 2k for the agreed price, but then "dumps" the other 3k on China sites for 50-75% less than they sell from legit stores here. Factory has no R&D to recoup or marketing to pay for so can make very good profit. Thing is they are still the real deal just being sold underhanded or even illegally.

While in this situation the e-bay ones don't look like the ones on official site so prob a fake, I have purchased e-cig products here and then off a China site for 1/3 the price and compared them, and yep both identical right down to the anti-counterfit hologram seal on the box.

They do this with high end golf clubs.  You get exactly the same product from the same factory but at half the price.  Of course you have to try and buy in person to be sure what you are getting.  A popular item in Shenzhen.

Furutech does not sell on line.
Buy HOSPITAL GRADE outlets from an electrical distributor. These are the same as the ones used in audio power conditioners. In hospitals outlets are color coded for dedicated use with specific equipment.  They are all the same heavy duty quality.   ......and you can buy locally.
