Easy to use. Issued a funny smell but apparently very effective. Very light device. No cons. It looks very effective. My dad has been using it daily. He used to smoke a lot and now was paying the bill for that. Therefore, he had to start using a nebulizer. Either way up the stairs much stirring.... Easy to use. Issued a funny smell but apparently very effective. Very light device. No cons. It looks very effective. My dad has been using it daily. He used to smoke a lot and now was paying the bill for that. Therefore, he had to start using a nebulizer. Either way up the stairs much stirring. But now complemented by this little device has given more air and can climb stairs again without stirring as before. I recommend it, well worth it and not expensive. You can use it all day long.

When I saw this personal ion generator on DealExtreme I had to order it. I owned another one (different brand) several years ago. It cost around $100 and was ugly, black plastic and very heavy. This unit is small, about 2.25 inches long x 1.875 inches wide. It is about .5 inches thick. It is very lightweight. It is made of high quality, white plastic with white translucent plastic sides. There is a green logo on the front. It is a very attractive design. It comes with a turquoise lanyard, also high quality. It arrived in a cardboard box, inside a hanging plastic display case. It arrived in good condition. There is a users manual that describes how to charge and use the ion generator. You can charge it with your computer USB port or use a wall socket. It comes with a USB cord and separate, US style wall plug. The first charge of the lithium battery takes 4 hours. A green LED indicates the unit is charging. When you switch on the ion generator, the translucent sides light up with a bright blue LED. It is very attractive, and there is no doubt the unit is working. It generates a very strong stream of negative ions. Much stronger than the ion generator I have in my car (SKU 2148). When the battery needs recharging, the blue LED changes to red. I have asthma and I can attest to the fact that you will feel better using an ion generator. I also recommend this unit for people with allergies and for travellers. This is a great buy on a high quality, personal ion generator. Don't hesitate to try it, you'll be impressed. Read more
