I doubt this review will be be displayed on the website, given the ordeal I was subject to. While the website information led me to what seemed the correct Dyson vacuum replacement battery, upon receipt it was the wrong one. So, the ordeal began with needing "permission" to return it. Then paying for the return registered postage, then waiting for a refund, then getting charged a further 15% for some "restocking charge". For a battery that cost $65 plus $10.25 HST, shipping of $16.90, return shipping of $20.72, plus a 15% restocking charge, I received $59.90 refund for overall costs of $112.87!... Buyer Beware!
