Frequently Asked Questions

How often can I use this neck and shoulder massager?

You can use it daily or whenever you feel tension in your neck and shoulders. For optimal relaxation and relief, we recommend using it for 15-20 minutes at a time. Warning, it is intense!

Is it plug in or battery powered?

The device is powered by plugging it into the wall outlet. Batteries die too fast and would increase costs drastically for our customers.

Can I use this device on other parts of my body?

Yes! While it's designed for the neck and shoulders, many users love using it on their back, lower back, stomach area, feet, and even legs. Its versatility makes it perfect for targeting any area where you feel muscle tension.

Is it safe to use heat with the massage function?

Absolutely. Our massager is designed to provide a soothing, gentle warmth that complements the massage, helping to relax tight muscles. The heat function is adjustable, so you can choose the level that feels best for you.

Does it come with a warranty?

Yes, we offer a 30-day satisfaction guarantee and a paid lifetime warranty(if you chose at checkout). We stand by our quality, and if you're not completely satisfied, we’ll make it right.

Is this device loud when in use?

No, the massager operates quietly, allowing you to enjoy your relaxation without distraction. It’s perfect for using while watching TV, reading, or unwinding after a long day.

How does it compare to a traditional massage or spa visit?

While nothing replaces a professional massage, this massager brings spa-level relief to the comfort of your own home. It’s convenient, cost-effective, and designed to provide targeted relief whenever you need it – no appointments required!

Is it easy to take on the go?

Our massager has multiple intensity settings, allowing you to customize the pressure and massage strength based on your comfort level. Whether you prefer a gentle massage or deeper relief, this device has an option for you.

Let Customers Speak

The positive reviews I saw on Instagram and Facebook convinced me to give it a try, and I couldn’t be happier with my decision! I was honestly skeptical at first, but wow....Theriva has been a lifesaver for my neck! I spend way too much time at my computer, and this is the first thing that’s really helped. My shoulders don’t feel as tight, and I’m actually sleeping better.

The massager works. I have noticed an improvement on my neck and shoulder pain. Oh and also the free relaxation kit was a huge plus. I didn't realize how much lavender oil helps with relaxation! I use the other free gifts as well.

“Useful details on people management suitable for all levels of management roles. Good topics & course contents.”

I use it mainly for my shoulders and lower neck after my workouts, and it really digs into those sore spots. What I didn’t expect was how it’s actually helped with my posture. didn’t realize how much I hunch over until I started noticing the relief. Plus, the car adapter is a game changer...Wish I’d found this years ago!
