  7. Rated 5 out of 5


    I am so delighted & impressed with my new thermometer. I can’t believe how well made it is, how fast it scans. I keep taking my temp just because it’s so fun to use. Ps. Special bonus points for including brand new sealed batteries with it. No one seems to do that anymore so it was a nice surprise! Will buy more products from this amazing company!

    This thermometer works great. I’ve been using it for a little over a week and have had no problems. Very easy and quick to use

  9. Rated 5 out of 5


    Great product. Easy to use. Fast shipping (we are on the East coast). We bought two. Both read the temp of one person the same on both thermometers. Accuracy is nice. Will be buying for my home as well, seeing how we like them so much for my work place. Highly, highly recommend.

    I’m a delivery driver, during the pandemic I find having this thermometer is most valuable. Even though I take extreme precautions it still gives me a bit of peace of mind. It is so easy to use. I highly recommend this thermometer! The price, quality and ease of use is wonderful!

    Great product. Works super fast and silent. Great for taking a kids temp while they are sleeping. Super fast delivery considering I ordered a time when demand is certainly very high..

    Very pleased. Arrived on schedule (6 days from order date) to Boston. Works great. We did comparative tests with a contact type thermometer and temps were identical. We’ve also purchased 4 different thermometers from other suppliers to take employee’s temps and the iHealth thermometer by far works best, was the least expensive and the only one to arrive in a reasonable amount of time. Now, I’m going to order a pulse/ox!

    I have put the thermometers right to use in my dental practice. They are quite accurate and the no touch feature is game changer. I highly recommend this product!

    The PT3 thermometer worked well enough, but I was disappointed when I tried to use it with the iHealth app. Apparently, at this time the only thermometer that works with the app is the TS28B. I could not find that thermometer on the iHealth product page.

    • Andrew Hu

      iHealth PT3 is a no-touch thermometer without the app. We only have the TS28B which is an ear thermometer with Bluetooth but only for B2B solution business as we are opening SDK or API to other healthcare partners.

    I was skeptical that this was a scam site given how many of those have been popping up. Thankfully this site is legit! I received prompt communication and shipping/tracking status and my thermometer arrived in two days. The thermometer looks and works great. I would reccomnend to anyone that needs a fast and reliable company. Thank you!
