When you hand pack you can see it push the old grease out then you know it is good
I would hope one would wash out the old grease with solvent and inspect the bearing before repacking it.When you hand pack you can see it push the old grease out then you know it is good
Not that big a mess if u know how to !!.Grease = mess.
Maybe nitrile gloves and contain your work in a cardboard box.
Well, I'm going to do an experiment. I ordered the one on the left, it was only $7. I'm going to pack one set by hand and one set with the plastic cone shaped packer. Keep you posted.
So the verdict is, the cone shaped tool is the way to go. Very easy to use and took about 30 seconds to pack the bearing vs about 5 minutes to hand pack. Now, both methods got your hands greasy, so no shortcuts there. With the cone tool you still have to handle the greasy bearing, pack the hub, insert the bearings, etc. Wore nitrile gloves so no big deal. For $7, it was worth it I guess just to know the bearing was completely packed. Couple of pics below of the cone tool. Also my before and after front brakes.

Picture #1 shows the grease being forced out at the base of the cage, but no grease being forced out around the rollers in the cage. Looks like an incomplete job to me. It does not raise my confidence level in that bearing packer. I think I'll leave mine in the box and continue to use the old tried and true, palm of the hand method.So the verdict is, the cone shaped tool is the way to go.

Ahh, I guess a picture is not always worth a thousand words. Thanks for the explanation.I took pic #1 right when the grease started to emerge from the base as you stated. I wanted to show it's progress. Next few pumps pushed the grease through the roller bearings and the top part. The grease filled the whole bearing fully and very symmetrically. I pumped grease till the whole exterior of the bearing was covered then wiped the excess off and used it in the hub. I'm totally confident that the bearings were packed properly. No better or worse than by hand but just a few minutes faster. 6 of one, half a dozen of another.
