The lack of a display did not affect functionality in any way. A removable battery is, of course, cool, but a new one is still impossible to buy. Has some pros: The vacuum cleaner is great. Comfortable, stylish and functional. A charge in turbo mode is enough for an apartment of 60 sq. m (about 10 minutes) Has some cons: Stopped working after a day. Sent under warranty to fix. They repaired it for 4 months (and this is in Hong Kong), but they fixed it (something with brains). Now works.
