Infinity Pro is fantastic!!! Cool design, variety or choices, provide warranty, and it is the world’s highest negative ion’s power bands, these attracted me at first! I bought a ionic power band for my mom who works from 5am to 11pm everyday, doing housechores and taking care of four babies. After wearing Infinity Pro power bands, she woke up the second day and told me that she just had the best sleep ever! She slept so well and felt fully recharged the second day! My spouse who is a fashionista and she always complain about her sore legs caused by really high heels. I gave her a Magnacore magnetic power and after a week of wearing it, she said that she could wear high heels for a long period of time without any soreness. My spouse who had doubt about infinitypro has now nothing to say but believe in its pro-ness! On top of that, I like its highly effective service We communicated via e-mail and I think their customer service is 24⁄7. Thanks Robbie for replying my every E-mail efficiently and guiding me until the parcel reach me, and also provide after sales services PERFECTLY! When I received them, there is two power bands have a little stains, and I took pictures and ask whether it is normal, in the next e-mail they replied with apologize and asked me to confirm with them the color and size because they are going to replace me both with new bands, and they send out directly! I was like. HUH? WOW? WHAT?! GREAT!, infinitypro is the 1st company I met who treat their customer so good lyk no one else. They replied asap at whatever hour I sent an e-mail. They responded to my requests and inquiries patiently and professionally. Thumbs up for their product and best service given! WORTHIT !!
