Questionable Quality

I purchased a lithium-ion impact driver CIRLI2028 almost a year ago, and it performed flawlessly the first time I used it. However, when I attempted to use it again, I was unable to remove the previously installed driver bit from the hex shank and also experienced difficulty inserting other driver bits. I am using the correct 1/4" bits, and this should be a straightforward replacement process. Unfortunately, I no longer have the purchase receipt. Based on this experience, I would not recommend purchasing Ingco power tools.
