1st, it's overpriced for what you get. 2nd, Dremel has really lost its quality. I have an old 4000 that is still running strong after 20-25 years. I was not too happy with Dremel's quality at that time, but it was the only proper rotary tool option for average home hobby work. The 4000 had its problems too. It had the easy open spring hinged brush doors that broke very easily. As it was the most powerful option at the time, I just took the whole tool apart, cleaned it out, greased the bearings, and took heavy weight, non conductive fishing line and wrapped the housing to prevent the brush doors from popping open. I would cut and replace the fishing line when I needed to replace the brushes. It was no longer noisy and had far less vibrations.
I wanted to get back into my hobby work full time, but was completely disabled 3 years ago, and only recently, have I been able to use my hands to do hobby work on a more permanent basis and wanted a new rotary tool. I bought the best Proxxon and Vevor rotary tool (I wasn't spending $600 for the Foredom), but I still wanted to have the accessory options that Dremel provided.
So, I purchased this 4300 with this case and accessories. I really like the case and a few of the accessories. There are things like this little light that is a joke, the handle accessory is a joke, but the worst thing about the whole package is the 4300. What is wrong with Dremel? This 4300 feels cheap and runs about as smoothly as an old farm tractor left out in the environment for the last 60 years. I did what the instructions stated. I ran it on the lowest and highest speeds with no bits and no load for the proper amount of time. This tool vibrates badly and is very noisy. It looks like it will have an early surgery to clean it out, grease the bearings, and try to balance the motor and shaft. If not, I doubt it will run the full time of its 2 year warranty, which is why I bought the Walmart extended warranty, just in case it destroys itself in the very near future. I want to like Dremel, but their greedy corporate officers must really hate their customers. I wish Proxxon would start making more options and accessories available to push Dremel into bringing back quality made tools again, either that or Vevor going all in and making budget quality versions. If Dremel doesn't watch out, customers complain enough, and ultimately customers just start seeking different options, places like Walmart, Amazon, eBay, Home Depot, Lowe's, etc. will drop Dremel from being able to sell on their sites and in stores. Customers really don't want this. Come on Dremel. Do better. You can't even buy the 4300 as a stand alone new tool. For this price in any package deal, it should be quiet and vibration free. It really sounds like a classroom of 1st graders torchering their parents with kazoos at an elementary school music program. Also, there's no need for the inflationary prices.
