AVICHE M5 Necklace Wearable Mini Personal Air Purifier with USB | Negative Ion Generator | Purifies Air Eliminating Germs, Dust, Viruses, Bacteria, Allergens, Mold, Odors, and More (White)

I've used a few of these wearable ionisers and this seems to be a winner in my opinion. Long battery life, about 3-7 days depending which setting you use. I have noticed it switches on and off each second so that's how the device is able to achieve long battery life.The land yard is adjustable if you want the ioniser closer to your face to get the Ions. It's detachable so you can use your own.The ON button feels firm and seems it would last a long while if you take care of it.The green and blue LED is bright so people are going to notice it around your neck.No electric shocks to the neck either.

Even probably when the Aviche M5 became faulty within 4 days Aviche has still refused to refund or replaced (I wanted a replacement because a replacement would cost probably at least an extra £11.00 sterling)NB! Should be banned from selling anything on any Amazon' websites.People shouldn't buy any Aviche' products unless they have to!End up with a piece of junk before, and after the 30 days period.Edit:Don't know if 1st review will be replaced.This is the 2nd Aviche M5 purchased probably received 24/1/2023, because had a cancer Appointment with Uro-Oncology, Cancer Consultant on the 23/1/2023.That already after leaving it to charged for 24 hours have stopped working (beeping, or hissing) out of it.Hence, sent another reply to Aviche M5 via Amazon UK's internal website page.managed to also find an email address to Aviche.ph.Posted a complain to Aviche's CEO c/o (care of) Aviche.ph also.Aviche's official company's website wanted me to contact Facebook, and installed Messenger app via their CHAT that did work also.Uninstalled both Facebook, and Messenger for security reasonsBut can't post this message, because may have exceeded the characters limitations if there is one.But Aviche should be banned from selling products in the UK, if necessary, and maybe all Chinese And Japanese products from being sold on any Amazon's website in the world.Edit: 05:27 26/1/2023Amazon's Order History statedordered Aviche M5 on the 24/1/2023,Delivered yesterday, 25/1/2023.

It works but beware if it swings round and the point touches you it hurts. I've attached a piece of plastic to the front to stop it touching me.

It's a small gadget almost an accessory. It just makes that beeping sound all the time. It's not silent at all. It's tolerable after a while though.Otherwise, will see how this gadget will be helpful overall.

Great principle but this beeps and flashes! No good if you prefer not to be conspicuous!

ETA 2021: Since buying this AVICHE M5, it emits a high-pitched, irritating bleeping whine that may be on the edge of peoples' hearing spectrum, nevertheless it's very annoying and especially at night.2nd Edit 16th February 2023.Shortly after I posted this original review, the seller refunded me, which I thought was generous. Also I was allowed to keep it, and to my surprise, 2 years later this high-pitched whine stopped. Honestly, I don't know what caused the whine, but am very pleased it's finally stopped.Because of this, I've reduced its rating from 5 Stars to just 3.

Does exactly as described.
