I purchased this product and received it yesterday 2/7/2020. It looked solid for the price. used it on 2/8/20 to drill (2) holes in brick and concrete blocks. It came first with a MG 1.0 metric screw that won't go through the hole you drill (why not a socket head set screw. The screw will vibrate after a few turns. There are 3 bits included. I quickly found out why The shank tip along with the adjusting bolt was lost in concrete blocks It can be a good economical product if the shank and part of the shank are brought back to the drawing board At the moment I would not recommend this product.
