Over the years, many customers of our previous web shop have shared their experiences with HSC products. We have now moved them here so they stay in one place in the new ALC store.
The reviews are published anonymised (first name and place), some are shortened or translated, without changing their meaning.
HSC protective smart card
“I ordered HSC smart cards for my office and home, and for our mobile devices. Shortly after placing them, the overall mood at the office and at home improved, and my sleep, which had been a problem for a long time, got better. I warmly recommend the HSC smart card to everyone.”
Tamara, Zagreb
“I use the protective card on my phone and it's excellent! During calls I used to switch the phone from one ear to the other because of the heat. A few months later, calls feel completely different and normal, like on a regular landline phone.”
Antonija, Zagreb
“After just a few days I noticed the devices heated up less and my ear no longer burned after numerous calls. I bought cards for my whole extended family, and I love giving them to friends and their children as gifts – people are genuinely delighted.”
Tanja, Radovljica, Slovenia
“My phone heats up much less. I got cards for the whole family and placed them on other devices too (tablet, Wi-Fi). Everyone I recommended or gifted it to gave positive feedback. Thank you!”
Martina P., Zagreb
“We are very satisfied with the product. We use it on all our phones and tablets, and the devices never heat up!”
Marija, Dubrovnik
“Dude, this chip is the real deal. My Samsung Galaxy S22 Ultra got so hot I would never keep it in my pocket. After using that little sticker, it took away all the heat. It works, and I'm shocked – very, very happy shocked.”
Martin, USA
“I was skeptical at first, but the HSC card really works. My wife and I both feel the positive effects, especially less stress and better sleep.”
Johan, Stockholm, Sweden
“The HSC card has made a noticeable difference in my concentration and focus at work. I no longer feel as tired by the end of the day.”
Katarzyna, Warsaw, Poland
“I have been using the HSC smart card on multiple phones for a long time. I trust the tests that were carried out and will keep using the card.”
Sergio, Split
HSC correlator – scalar needle
“After a month I didn't notice much, and after five months I was already thinking about a return. Today, more than two years later, I use my scalar needle daily and wouldn't trade it for anything. I even gave it a name :-) Thank you to the HSC team.”
Zdenko, Varaždin
“I have been feeling great ever since I started drinking the water. I sleep much better, I can concentrate much better, and I feel content in my body.”
A. M., Budapest, Hungary
“At first I hesitated because of the price, but some things in life simply don't follow those criteria. The needle isn't a magic wand – I use it briefly every day to raise the vibration of water and my own energy. I feel energized, youthful and strong. I recommend it to everyone with patience.”
Denise, Rijeka
“Priceless.”
Isabella, Sydney, Australia
