This is a FRAUDULENT seller and a FRAUDULENT web site (Period). Here is a summary for anyone who has been (or will be) scammed by this Online retailer: Order No. 8005107476775871: ON Nov. 14 2019, I received this order and immediately realized that IT WAS NOT WHAT I ORDERED. So, I sent the following message to the seller (through ALIEXPRESS web site): The ordered product clearly states: FLEXTAILGEAR - MAX Pump 2 Portable Air with 3600mAh Battery USB White.....What I received is NOT MAX PUMP2 IT IS: LIGHT PUMP2 AND IT IS NOT BATTERY OPERATED. This is a WEAK PUMP that only works when connected to a USB adapter. I have no use for this device. Please send me WHAT I ORDERED, Period. I also attached two photographs showing the wrong "light pump 2" In response, The seller (and this incompetent website) asked me to return the WRONG product AT MY OWN EXPENSE and send them a tracking number in order to get a refund (They did not even offer to send the CORRECT PRODUCT!) On November 15, 2019: And as directed by Aliexpress: "If you wish to contact the seller, Skiyomi Store," I wrote another message to this corrupt seller as follows: Please explain this to me: If the wrong product was sent to me because of YOUR FAULT. Why do you expect me to spend my own money to return your useless product and receive a refund? If you do not send a pre-paid shipping label, I will escalate this dispute even if of costs me 1000 times the original purchase price - I GUARANTEE IT. Needless to say, I received no response (what-so-ever)! On november 17, 2019: I sent the following e-mail to ALIEXPRESS followed by a complete summary of this FRAUDULENT TRANSACTION: This e-mail shall serve as my last (and only) notice of fraudulent activities committed by you (or one of your sellers). You are, Hereby, directed to immediately intervene and resolve this matter. Otherwise, The undersigned shall pursue this fraudulent activity to the fullest extents of the laws governing commerce in the state of Florida, USA. Needless to say, I received no response (what-so-ever)! However, I continued to receive e-mail reminders to send them a return tracking number, etc……….! EVERY ONE WILL BE (VERY) WELL ADVISED TO AVOID ANY TRANSACTIONS WITH EITHER SKIYOMI STORE OR ALIEXPRESS.
