Unique and stylish presentation. However, when spending $50,000 on a vacuum, you have higher expectations. Benefits include the convenience of wireless connectivity. It's incredibly practical. When I accidentally dropped something, I quickly retrieved a vacuum and cleaned up the mess. The negatives are: Weight and comfort in use. I initially felt the reviewers were being very picky when they pointed out issues with the pen. The pen is terrible, I agree. The trigger is buried so deeply that you have to curve your finger to pull it, and it's thin, slippery, and lacks finger holes. The unit's considerable weight makes it difficult to use for long periods of time without experiencing hand fatigue. Where exactly are you aiming your "gun" mode and pipe vacuum cleaner? To prevent the vacuum cleaner from spinning or falling out of the brush, extra effort is required, and the brush cannot be securely fastened to the handle. Why the engineers didn't prioritize ergonomics is beyond me. It is, to put it mildly, a thin, slippery, elliptical bowl made of plastic. One day I hope to adjust to it. However, after 15 minutes, the pain in the hand becomes severe. The length of the pipe is fixed and cannot be altered. Also, the power source (battery). Do not rely on the stated time. It will take no longer than 15 minutes at full power. About one hour, using minimum power.
