No. This skimmer is one of the oldest, least effective, models on the market today. The quality of the skimmer is determined by the amount of bubbles inside the chamber, the size of the bubbles (smaller is better), the "contact time" between the water and the bubbles, the neck restriction, and the user friendliness of the overall design. The Lee's model internal counter current skimmers rate near the bottom on each of these categories. I am speaking from first hand experience.
If you need a low cost skimmer with minimal acceptable performance, check out the SeaClone model hang on skimmers. The contact time is adequate, they use a venturi intake which produces quality bubbles, the neck width does not restrict the output to any significant degree, and the collection cup is easily removed. It is difficult to control the water level inside the skimmer chamber to achieve a good paste in the collection cup, but this can be improved by adding a wooden airstone into the skimmer column, or by switching out the power head for a needle wheel model. If your budget is under $100, this skimmer is the best I have seen for a hang on model.
If by some chance you have a sump system, then you could consider the Odyssea skimmers which are sold on ebay. These units are a pain in the rear when used as a hang on, but are adequate when incorporated in the sump. I am still using the Odyssea PS75 on my 58 reef (in a sump application), and I can't complain. I paid $35 including shipping and power head.
