I have one. It is nice, but also a "get what you pay for" exchange.
It's just big enough to not fit well in my medium size range bag, but I can get it in there. The bag it comes with may or may not fit the forarms of your rifle. It's too wide for my Hawkeye but fits the Boyds' Classic stock. It's fitted with velco straps that I could not get tight enough to prevent easy lateral movement. So I put some duct tape under it so as not to worry about it, and gives me second thoughts on buying extra bags with wider/narrower notches.
I thought Caldwel was American but was disappointed to find that it was made in China. It's also cast iron, so does not take to rain well. Honestly, when I go to the range, it's a coin flip as to whether I pack up the Rock Jr. or just use the range's rests and bags.
