Tremelo Testimonials

Our customers want you to know their experience!
"One of the hardest things is eating, drinking. This makes it so much easier. I’m not spilling stuff everywhere."
Patrick Hallmark
Hallmark suffers from Essential Tremor and Parkinson's Disease, but has recently been helped by Tremelo.
“Though a touch bulky, the Tremelo gave me a stability I haven’t experienced for months and months.”
Judith Dahlberg (California, USA)

“Just had to let you know that the Tremelo is really helping my husband with his tremor.”
Gladys Haynes (New Jersey, USA)
“The Tremelo has just arrived! My wife has put it “through its paces” and is thrilled with it. As in the documentaries, drinking from a cup, putting a spoonful of cereal to her mouth etc. is no problem. Also, measuring ingredients when cooking is no problem.”
Grahame & Robin Waters (Western Australia, Australia)
“So far, my Mom loves the Tremelo. She has essential tremor in both hands, but wears it on her right, since she’s right-handed. It works like a charm. ‘I can eat soup!’ she says.”
Ann Zweig (Kansas, USA)

How Tremelo Works

Tremelo uses Tuned Mass Damper technology to mechanically stabilize tremors. Simply, the wearable sleeve uses a built-in small mass that shakes back and forth against the tremor motion. Tremelo uses the principle of energy absorption — normally found to steady planes, bridges and tall buildings — to counteract the shaking in hands.
