Good rotary at a good price
I purchased this rotary in order to learn how to use this type of polisher and deal with the benefits as well as the shortcomings. I have a Flex 3401 and a Griot's Garage 6 inch, so I wanted the experience of a rotary. Right away I noticed how this type of machine can quickly erase imperfections that can be beyond any random orbital polisher's capabilities. Water spots that I just could not get out of my hood with either the 3401 or GG 6" disappeared after a couple of passes with the 3403. So having a rotary AND a random orbital can have it's advantages if you are careful of the harm that can occur with misuse of a rotary. I have to say that I'm satisfied and glad that I picked up a rotary polisher.
ProsThe correction and leveling ability of a rotary polisher is something that I think is still beyond random orbital machines.
ConsThe trade off is the harm which can occur if the rotary polisher is not correctly used. Holograms can also be left on a paint finish. The experience of developing one's technique with a rotary polisher is something I had to experience if I wanted to continue my evolution in detailing.

Flex L3403
Very light weight, yet powerful. Handier than a full size rotary, great for boats.

Very disappointed
I am very very disappointed in this polisher. I loved the size of it and the weight. It was pretty much exactly what I was looking for. I polished three cars with it, and polished my boat with it once. On my second time polishing my boat I noticed the black part of the housing getting hot. The next day when I decided to finish the boat with another pass of swirl remover, the black casing got extremely hot to where I could not hold it, so I shut it off and let it sit while I ate lunch, then came back and it would not start. This polisher is not old at all and has very little run time on it, but I still had to break out a ten year old Makita to finish the job. VERY VERY DISAPPOINTED. I have cyclos that are 15 years old and still run perfect and this one could not even make it through 20 hours of run time.

flex light weight
It is good enough to get the job done, but the downside is the handle is too big and not as comfortable as the mikita and dewalt.

Amazing machine
We bought this machine for the light weight and because of Flex's excellent reputation. We already own a 3401 and love it. The 3403 is so lightweight and quiet it is hard to believe it is a rotary polisher! Yet it removes defects and levels paint just like all of those heavy and bulky models. Best money we ever spent!

Flex light weight
Great for side panels because of the weight. It's a whopping 3.5 lbs. iighter than the Dewalt and 2 lbs. lighter than the Makita.

Excellent Rotary
The Flex is a great new addition to the rotary buffer field. The weight difference between it and a Makita is noticeable (almost 2 pounds). The only problems I've noticed is that the lowest speed is relatively high (1100 rpm). Also, for the first 50 or so hours on the machine, it can get very hot. However, that problem seems to correct itself after the break-in period so it isn't a very big deal. Overall, its an excellent machine and I'm very pleased after purchasing it.
