> 3 dayWorks intermittently. Same battery different battery clean filter dirty filter runs perfect one time then the next runs for 4-6 seconds and you have to wait 10 seconds for the vacuum to work again. Pass

> 3 dayWish I would have dug deeper into the reviews before purchasing. The adapter is easy to install, and fits the Dewalt batteries without issue (which is why it gets 2 stars). But it will not work if your vacuum is set the the Max Suction setting. It will only turn on for 1 second, led goes red, and immediately turns off. Works just fine if you use the lower High Suction setting, but without the ability to use the Max setting (even from time to time)... is a deal breaker for me. Thats the whole reason I bought a Dyson in the first place!!

> 3 dayMy OEM battery would only last a couple of minutes, so this allows me to use any of my numerous deWalt batteries and just swap n another one if I run out of juice -- much better utility if a little bulkier than original.

> 3 dayAmazing, it works perfectly. Used the screws from the original dyson battery instead of the supplied ones since the original were longer. There wasnt a ryobi attachment one sadly but purchased a dewalt slim 4ah and battery charger. Purchased dewalt battery from home depot - too many fraudulent ones on amazon. Dewalt website states that they do not sell on amazon. Dont throw the old dead battery in the trash. Take it to free electronics/hazard recycling or drop it off at work by your battery pickup area.

> 3 dayMy Dyson vacuum works better with this adapter and a Dewalt battery. Much better than the original battery. Go figure with the cost of a Dyson!
