Review on High Performance 4.0Ah KUNLUN V7 Replacement Battery Compatible With SV11, V7 Absolute, Motorhead, Fluffy, Trigger, HEPA, Car+Boat Vacuum Cleaners - Includes Bonus Filter & Brush by Osoulo Sharp

I had originally submitted a poor review of this product because it appeared the battery was only holding a charge for a few seconds after I installed it. After my review was received the company immediately contacted me to offer me a refund or replacement. I appreciate your willingness to work with me on the replacement battery. I decided to further investigate the Dyson vacuum and discovered their was a large clog in the vacuum head that was the problem. I was able to thoroughly clean out the unit and have been able to use the vacuum again with no issues. The new battery I purchased from seems to working correctly now that the clog was removed. I appreciate the company reaching out to stand by their product and would recommend this replacement battery for the Dyson vacuum.
