I have the Kenmore versions of the Duets, the HE4Ts. The only problem I have with the dispenser is adding the bleach as you mentioned so instead of pouring right out of the bottle, I just pour into a small measuring cup first - problem solved. The dryer works great. The clothes always dry quickly. For the most part I use the auto cycles and the clothes are dry in 30-40 min with a full load. As for the lint filter, I find it very easy to remove and replace.
