Customer photo review of Hedron Black Guardian

Is this thing supposed to lean to one side? It looks ridiculous. Whoever ground the bottom during manufacturing certainly took no care in ensuring this stood straight like in all your images on your website. Additionally, this thing arrived wrapped in thin cardboard with two small pieces of bubble wrap laying loosely in the box. You say you offer no warranty returns due to the delicate nature of the crystal, then why not package it so it can’t get damaged. The box was all crushed as well. Communication with your company has been abysmal. After you told me my product was on the way and when it was expected to arrive and it didn’t, I reached out to you with phone calls and left message but no one called me back. I had to reach out to the clinic that recommended your product to see if they had a contact within your company that they could notify as I had not heard anything. Alas, you then sent me a benign email with a poor excuse that you were eager to get me my product so a label was printed but no product for nearly a month. Can’t say I’d recommend this product or your company based on my experience. Since you say I can’t send this ridiculously leaning crystal back. I’m stuck with a $600+ eye-sore.

Hedron Black Guardian

I've only had the harmonizer on my laptop for about a week; not enough time to really notice changes. I think I'll notice after more time. Expecting to notice changes in my energy level while working on the laptoop.

Hedron Pendant

Hedron's products are high quality, and game changing.

Hedron Pendant

I was really excited to receive this. However once I did I was really disappointed. There were so many air bubbles and so much fogginess. I have had so many compliments on my other one, but this one did not live up to expectations at all 😒

Store owner replied: We are so sorry to hear that you're unsatisfied with your pendant. Each pendant is unique, so the colors, patterns, and overall appearance can vary from one piece to another. No two pendants are exactly alike.

I like me the pendant but the silicon lace is too short. Wondering if I can use a cotton string?

Hedron Pendant

Store owner replied: Thank you for your review! We are sorry to hear that! Yes, you can use a cotton string or a chain.

We have used Hedron products for years, and we love them! The new smaller design is a great fit for my phone.

Customer photo review of Hedron Pendant Replacement Silicon Cord ONLY

It’s too short, it breaks every time I put it over my head. I have neuropathy so my hands don’t work so well in putting it back together. I need another 3 inches added to it so it can easily slip over my head. Please and thank you.

Hedron Pendant Replacement Silicon Cord ONLY

I love it. I’ve had mine for several years. It has helped me with not getting headaches when using my cell phone. This time I purchased cell phone EMF Harmonizers for my daughter and son.

5G Elite Cell Phone Harmonzier

I had to upgrade my cell phone to 5G and could feel the draining energy in it while I held the phone. Now with Hedron I feel it's neutralized.

5G Elite Cell Phone Harmonzier

Works great to replace the original one that broke after wearing it for a year. It’s thicker than the original too so it looks like it will last longer.

Hedron Pendant Replacement Silicon Cord ONLY

I’m very happy with my pendant cord replacement. It arrived quickly too. I have been wearing my pendant for many years now and believe it helps protect me from radiation exposure. I feel better when wearing it. It also makes a good conversation piece.

Hedron Pendant Replacement Silicon Cord ONLY

Love the smaller Hedron! Fits nicely in the upper corner of my iPhone, out of the way from the wireless charging area.

5G Elite Cell Phone Harmonzier

I experience a weird type of discomfort in my hand when I hold a phone. No matter how I hold it, I experience the discomfort and the longer it's held, the more intense the discomfort gets. That's been my experience with the past 4-5 phones that I've used. Unfortunately the Hedron device hasn't done as well as I hoped. It does help a little bit but it doesn't completely protect me from the complete experience.

5G Elite Cell Phone Harmonzier

My phone would heat up and get hot and I could feel tingling in my finger fingers when holding the phone. After applying the device to my phone, those symptoms are not there.!

5G Elite Cell Phone Harmonzier

I tried to give you a photo, but it wouldn't take it some way. It wouldn't process it through. Anyway, I really like the pendants. My wife and I already have one apiece and the harmonizers, but it's good to keep a couple extra. It gives us some peace of mind to have the protection! Thanks!

Hedron Pendant

I love my Hedron for large electronics! I put it on the back of my iPad and I am feeling much better; and my iPad runs better as well! I already have the Black Guardian (as I live about a mile from an electrical substation and cell tower) and the IResonate black pendant for personal protection. I have had both of these going on 3 years and there is such a difference in the atmosphere of my house - much calmer. Thank you for such a great product and resources for this largely unknown issue.

Hedron Harmonizer for Larger Electronic Devices

I'm highly sensitive to emf's and I feel the difference immediately using the Hedron emf protection.

5G Elite Cell Phone Harmonzier

We have placed the home harmonizer on our living room coffee table where we constantly use our phones, tv and other devices. Our Wi-Fi monitor is located not more than 10 feet away. We felt this was ideal for us. Our bedroom is free of such devices and are our phones rarely ever used here.

Hedron Home Harmonizer

I have noticed that wearing the Hedron pendant, I have much more steady energy now and I am sleeping better. Those 2 results are worth a lot! I also have a great sense of well-being, which is wonderful.

Hedron Pendant

I peeled the clear plastic off the front and it sticks to table or anything I rest it on. It’s on the back of my phone case.

5G Elite Cell Phone Harmonzier

Im pleased to replace our pendants. However, the design on the front of my pendants is not the same as the design pictured. The reason we've replaced our pendants is because the black ring molded in the pendant casing has broken. This also happened to a friend's pendant. Apparently after several years of wearing the pendant, this black ring weakens and breaks so the pendant cant be hung on the silk chord necklace. This must be a design flaw or the molded ring is fragile and eventually breaks over time.

Hedron Pendant

Store owner replied: Thank you so much for your review! 💛 The pendant design you received looks a bit different because we’ve updated to our newest style — the one currently shown on our website. Our previous version sometimes had an issue with the molded loop wearing down over time, so we changed the design to make it stronger and more reliable for everyday use. — thank you for your continued support! 🌟

It's my second order of these but this time for a family member. Hedron is a great source for these items!
