Wasn't your company called ENDEVR and LifeStrength before?

Yes! Our original company name was LifeStrength back in 2010. Then several years ago, we changed the name to ENDEVR because of our expanding product base. Now that we only provide our PureStrength ion bracelets, we think it should be called just that—PureStrength. 

What size of a band should I buy?

There is a sizing chart located on each product page.

Can I get my wristband wet?

Yes. Our technology works in water and the products can be hand washed and air dried. Do not machine wash or tumble dry.

How long does my wristband last?

Our products are constructed of high-quality materials and designed to withstand daily use. Every PureStrength™ wristband comes with a lifetime warranty for manufacturer defects.

Can I wear it 24 hours a day?

Yes, but every person is different. Some people prefer to wear their wristbands 24 hours a day while others wear it only while participating in daily activities.

How should my wristband fit? Does it need to touch my skin?

The fit is a personal choice and should be comfortable, but not too tight.

Can anyone wear the wristband?

People from all walks of life including small children and the elderly wear PureStrength™ products.

What if I have a known silicone or metal allergy?

Some of the minerals we use are metallic in nature. If you have a known metal allergy, do not wear our products. Also, many of our products are made of silicone. If you have a known silicone allergy, do not wear our silicone products.

Will my international order have customs or brokerage fees added onto it?

Possibly. Packages that are shipped from one country to another can have brokerage or customs fees added onto them. The person receiving the package is responsible for paying these fees for customs clearance. Customs policies vary widely from country to country. These fees are imposed randomly and at the decision of the specific country and post office that is accepting the package. We have no control over these fees and cannot predict what they may be.

If I haven't opened the product and would like to send it back, can I refuse the package or just write "Return to sender" on it?

Any mail that is refused, or marked "return to sender" or sent "postage due" will have a deduction of that postage amount from any refund. We regret any inconvenience this may cause.

If I am charged any customs/import fees, does PureStrength pay for that?

PureStrength is not liable for customs/import fees that may be applied to shipments outside of the US.
