Review on EWK 64 5Mm Removal Corolla Cylinder by Marvin Short

I've just received one of these, or at least one that looks very similar and comes in EWK packaging. The problem is that the hex nut fitted on top is NOT 27mm long as described here. My 27mm head is way looser than it should be. As you can see from the pictures, there is no EWK engraving or stamping on the top. Could I get another one but sent it back in EWK packaging? I do not know. Edit: Went out today to see if I could find a hex head that would better fit the head of this wrench, to no avail. 27mm or 1 1/16 is too loose. The next size does not fit. 1" was too small and I couldn't find a 26mm or 1-1/32" socket at my local store, so I ordered a 26mm head from Revain. It should arrive in a few days. If this is the case I will edit this review Edit 1/2/2020: See my short video for the results The 26mm socket fits the oil filter cover wrench much better than the 27mm socket pictured.
