Review on 🌬️ 4WDKING Rechargeable Electrical Air Purifying Device with HEPA Filter for Sleeping, Outdoor Sports, Housework - Portable and Reusable with Extra 10 Pcs Replacement 5Ply Filters by Sandi Alexander

I have no problems with the function of my order received from 09/01/20 - the devices appear to be well made. Like many other people, I was curious as to whether the case is aluminum or plastic. On 08/30/20 the seller answered Jaime's question on how to get the metal case: The metal was $70 vs $50 for the plastic case. I decided to take what I thought was 1 metal and 2 plastic units ($79 and $60 respectively) to compare. What I didn't realize was that the same day I ordered the metal products were discontinued (you'll have to read all the review and question pages to find the ad - it really is buried somewhere). I think the seller could have communicated this better by indicating this change on the product page in a timely manner. I thought at first that my order was filled out incorrectly. However, the price of $79 reflects the receipt of 10 additional plastic block masks. Deducting 2 stars for pulling out some of my hair!
