He'd rather just criticize and insult people.
On topic....While this seems like it would work ok for certain situations, it is definitely no replacement for a real winch. I agree with ealier comments that if you are in places that you might need this, then you need a real winch and even though it is a larger investment, a real winch is worth the extra expense.
the size is a big factor too. A bumper mounted winch is probably heavier overall (assuming it has wire rope) but it's outside the truck and doesn't occupy space used for other gear like this would. It's a pretty large and bulky kit.
I think anyone would be better served with a real winch and a pullpal.
