Kiierr International LLC Tracking Order Status

Easy to navigate site. Helpful chat while making order. Fast shipping and the product arrived as described. The cap fits well and seems to be working as it should.

I purchased the Kierr 302MD. The cap has been super easy to use and only takes 6 min/day, so it has been easy to incorporate into my daily routine. It was very simple to use out of the box. The battery is lightweight and holds a charge for 5-6 uses. I did not give 5 stars because the cap took a few weeks to arrive, and Kierr was not clear about how long delivery would take. Everything else has been excellent and it was easy to apply to my HSA account.

Great experince so far. I let Kiierr know I did not receive the headband and it was on back order. Then i received it about a week later. So far, great customer service! Too early to tell on how well this will work.

The item shipped when promised and came with simple easy instructions and a great box. Everything has been super easy for far.

Just received my cap and I'm positively surprised with the quality of the cap. Looking forward to see the results in the upcoming weeks.
