This is a great Cordless Stick Vacuum.   It was very simple to put together.  I had not problem following the instructions.  They were very clear and easy to read.  The vacuum came charged so I was able to use it right away.  Once it was put together, I found it very light to use.  It had a good amount of power.  It picked up whatever I had to vacuum up.  It was also good that there was no cord to trip over.   I could move around the whole house with ease.  I also had no problem doing the stairs and carrying it to the second floor.  It was very easy to install the charger unit on the wall to hang the vacuum on so that it would charge for future use.  The additional tools also hand there for quick and easy use.  So far I would say it was excellent and has a great amount of power.    Purchase this vacuum.  You will not be disappointed at all.   I received this product at a discounted price in exchange for my honest opinion.
