This was a good tool to have for working on tiles. It can support a good amount of weight and is pretty easy to use. I also use the vibration to help with cleaning my car too. I use the vibration to dislodge the debris to make it easier to suck up with a vacuum. The vibration is not super strong where you have to worry about it breaking the tiles. This does make it easy to move the tiles safely into place. The devices itself is not too heavy. The controls are pretty straight forward. It is essentially just a two button device. You just have to scroll through what you want the intensity to be. The suction is just the same. You cannot control the strength of the suction. I am not too much of a fan of the top handle. It feels a bit flimsy to me. It is a solid plastic piece rather than metal. It is a simple level to activate or deactivate the suction. It feels like a bike brake. It does run on a battery. There are two batteries and it is charged by the usual DC plug. It is nice because you can use one battery while the other is charging. It is easy to pull the battery out and it is secure for the most part. The battery last for quite sometime on just here and there use. I was able to utilize it for several hours before I had to recharge it. It is not something that you need to assemble other than plugging in the battery. There is a storage case. It is a hard case storage box. The latch is not bad. I wish the whole thing came in a box but the latch was pretty secure. There are slots to hold the devices and accessories in it so you do not have to worry about things sliding around. Overall I was pretty happy with this vibration machine. To be honest, I mostly use the suction part to move tiles and glass panels. I only really use the vibration for cleaning. The charge on the battery last for quite sometime and it does not take too long to recharge (2-3 hours). The controls are easy to learn and the suction is pretty strong/secure.
