FAQ

A bracelet with HSC technology, inspired by Tesla's ideas of energy, frequency and vibration. No batteries, no chemicals, no charging. Wear it every day as a reminder to slow down and stay balanced.

Users most often report less stress, better sleep, sharper focus and more energy during the day – especially with a lot of screen time and travel. Experiences vary from person to person. The bracelet is not a medical device and does not replace treatment.

There are three styles: silicone (unisex, 11 colours), cord (women's – RUBY and LUNA) and leather (men's – METRO). All models carry the same HSC technology and differ only in style.

Yes. The bracelet is made for all generations – children at school and in sports, adults at work and in their free time.

No. It has no battery or electronics and works on its own.

Once a week, wash the bracelet under a stream of warm, soapy water – every style: silicone, leather and cord. Pay special attention to the metal part: remove the oils from your skin, then rinse and dry the bracelet well.

The bracelet works only in direct contact with the skin. Oils and dirt from the skin build up on the metal part over time and reduce that contact, so clean it regularly with warm, soapy water.

Silicone models handle water with no problem. We recommend taking off cord and leather models before showering or swimming so they keep their look longer.

Yes – the bracelet comes in a box, and with 14 models you'll easily find a colour and style for everyone.

Glasses with clear lenses, a frame with black lenses, a frame with yellow lenses, a microfibre pouch, a cleaning cloth and instructions.

Clear – for screens and artificial light. Black – for strong sun and outdoor sports. Yellow – for fog, cloudy days and driving.

Yes. The lenses have an EMI and Blue Glide layer that filters blue light from monitors, phones, TVs and LED lighting, plus UV400 polarisation (100% UVA/UVB/UVC protection) and anti-reflective coating.

Yes – they are light, with a stainless steel frame. Many people wear them all day at the screen and say their eyes feel more rested at the end of the day.

They comply with Regulation (EU) 2016/425 and standards EN ISO 12312-1 and EN ISO 12312-2. Made in Croatia.

The base frame with clear lenses weighs only 11 g, and each extra frame (black or yellow lenses) 4 g.

Yes, they can be worn with contact lenses and over prescription glasses. Handle the frames carefully.

We don't recommend wearing both frames together for long periods – each is made for its own conditions, so use them separately.

The box is 16.2 × 7 × 5.4 cm, with a gross weight of 210 g. A dimension drawing of the glasses is in the product gallery.

In a market test, 50 users wore the glasses for three weeks. 43 of them wanted to keep them and buy them at full price.

Clean the lenses only with the supplied microfibre cloth; if they are very dirty, first rinse them with lukewarm water and a little mild soap. Do not use paper tissues, clothing, alcohol or strong cleaning agents – they can damage the protective lens coatings. Keep the glasses in the pouch or case, never lens-down, and do not leave them in the heat (e.g. on a car dashboard in the sun). Put the frames on and take them off carefully, with both hands.

Yes – the Teslass protective case (15.5 × 5 × 4 cm) has an internal metal reinforcement, an outer cork layer, a soft lining and a magnetic closure. It is more compact than the original box and protects the glasses from impact. Sold separately.

Peel the protective film off the back and stick the card to your phone, tablet, laptop or other device. Picture instructions are in the product gallery.

Any mobile phone, regardless of brand or model, as well as laptops, tablets, TVs, monitors, Wi-Fi boosters and other devices that create an electromagnetic field when working. It is programmed for all network generations – 2G, 3G, 4G/LTE and 5G.

No. Stick the card directly on the device so it is in direct contact with it – not on a protective case, cover or similar.

If you charge your phone wirelessly, do not stick the card in the middle of the back, where the charging coil is – the card would then stop the wireless charger from charging the device. Place it closer to the top or bottom edge of the phone.

Yes, as long as the original adhesive tape on the card still holds well. The card does not work in combination with other adhesives.

The card has no expiry date. As long as it is not mechanically damaged (bent, scratched, cut, etc.), it keeps all its properties.

It is used with water, drinks and food before consumption, and as part of a personal relaxation routine. Users report a feeling of balance and freshness. It is not a medical device or a substitute for water purification.

Take special care of the tip of the needle. After every use, wipe the needle with a soft tissue and put it back in its case.

If the needle falls on its tip, it may lose its effect. Always handle it carefully and put it back in its case right after use.
