This product is extremely dangerous; I nearly lost an eye as the bit detached from the tool. It should be removed from Amazon until the constructor fixes its user manual.
If you bought this device, please watch this video before using it! I explain what is NOT written in the user manual, which is something that you MUST do before using this tool. Again, a part of the tool flew into my face.
I bought this on Amazon under the name "GOXAWEE Rotary Tool Kit with MultiPro Keyless Chuck and Flex Shaft -140pcs Accessories Variable Speed Electric Drill Set for Handmade Crafting Projects and DIY Creations".
Update: I disabled comments on this video. I received many weirdly aggressive comments against me. I do not understand why some people would be so motivated to go after me unless they were interested in defending this product? Considering the company making this device, GOXAWEE, received a C grade on Fakespot, I would not be surprised if they paid for comments to be posted on this video. https://www.fakespot.com/company/goxawee
