This buffer has plenty of power to get the job done, and appears to be well worth the money.  Some minor assembly is required.  There is a `manual' but it does not contain any instructions, instead it mostly covers general safety.  Assembly is fairly simple.  You first attach the curved top handle, either with or without, the straight side handle.  The handle can be installed for either right or left hand operators.  The buffer is top heavy, so installing the side handle is highly recommended.This unit comes with the accessories to get started right away.  For buffing, it has a wool pad, and rubber backing pad.  For sanding, a Velcro backed hard plastic disc is included, but you will need to provide the sandpaper inserts.  A special wrench for locking down the rubber backing pad is included.Controls are pretty basic.  There is a throttle switch on the bottom of the handle, with a lock button to keep the motor running.  The speed control dial is on the top of the housing, and goes from 1 to 6 (maximum).  The buffer starts to whine at around level 3, and gets screaming loud at full speed, when ear protection is definitely recommended.  The amount of vibration will vary according to the task, and motor speed.  When sanding or buffing fine dust is typically produced, so you may want to wear eye protection and a dust mask.If you are into weightlifting, using the buffer on a vehicle may not be too difficult, but for those not so physically fit, managing the weight and vibration, could be a challenge.  Because of the tool is about 18 inches long, your hands end up positioned about a foot apart, in order to keep the torque generated by the buffer under control.  Just a little inattention can result in losing control, or dropping the buffer, and you don't want to hurt yourself, damage your paint job, dent your vehicle, or damage anything else.The supplied wool buffer is quite thick, and does a pretty good job, but you do need to apply pressure for it to work.  For the average sedan, buffing the hood and trunk should be the easiest.  Things get harder when you do the sides, or curved or irregular surfaces, and have to both support the weight of the buffer, and apply pressure to the surface.  Buffing non-flat areas usually requires changing angles, and varying the point of contact, and amount of pressure applied.  Users will need to find the grip and techniques that work best.  Buffing will require some finesse at times, and if your muscles are straining, this is when accidents can happen, or you can hurt yourself.  Doing the roof can be tricky as well.The listed weight of eight pounds, may not sound like a lot, but if you are bracing your body, locking your forearms, and squeezing hard on the handles for an extended period of time, you may find your muscles a bit sore, or in `shock' from the vibration, if you overdo it.  Just go easy when using it for the first few times.The pictured buffer has a blue plastic housing and black handle, but the unit also comes with an orange plastic housing.  It has a ten foot cord with a twin blade plug, and comes with a set of spare brushes.  The buffer does produce very good results, so if you have a strong back, and the upper body strength, it could be a very cool buy.
