I don't understand the question, you only listed one scope?

What are going to use it for? Plinking on a .22/.17 or varmint hunting on a centerfire, or deer hunting.

If it's for a .22 it will be ok, but you could get better. If it's for varmint hunting I would save some money and get something better. A scope with those features and magnification for $100 isn't a very good bargain in my opinion, just a cheap scope. A decent scope with those specs is going to be in the $300 to $400 range and good scope is going to be closer to $600. In order to get the price down that low they had to cut corners somewhere, and it will be in the optics and quality control. just go to a store and pick two 20 power scopes, turn them all the way up and look at something far away. Pick one cheap scope and the other a quality scope in the 250-300 dollar range. If you don't see a difference in optical quality you should see about getting your eyes checked.

Now if you are talking about putting that on a deer gun, that is waaay too much scope unless you are shooting them at 600 yards or something, and then you will need a much better scope. For deer look at scope closer to 2-7x32 or 40 or the old stand by 3-9. Even a fixed power 2.5 or 4 power will work well if your not shooting very far. The lower magnification will let the scope seem brigther and more clear, plus keep price down. You can get some pretty decent low power variable hunting scopes for 100-200 dollars. Skip all the bells and whistles like illumated reticles, Ranging reticles and parallax adjustment. You don't need them and they will either increase the price or decrease the quality. Worry more about optics and coatings.

For a liitle more money you could get a Nikon Pro Staff or Bushnell Legend in 2-7 power and it would be a MUCH better scope optics wise. Jump up to the $200 dollar mark and there are many more options that are really good scopes as long as you keep the power and objective lens conservative.

You really owe it to yourself to go to a store that has lots of stock and look through some different scopes. I would never buy a scope mail order unless it is a model I have already owned, and then I would still really like to look through it first. I have a mueller I am pretty happy with as well, they make a decent scope for a decent price. I got mine at Gander Mountain.
