I have a nice yellow one that's 30 feet long. It's great as long as you are going straight with it. You can't "bend a leg" in it like you can with a steel tape, so I stick with steel ones for routine fishing. The fiberglass one is really nice if you are, say, fishing across a ceiling since it stays flat instead of possibly coiling like steel tapes can do. Remember that fiberglass tapes are a bit stiffer, so working with 1/2 or 3/4" pipe might be tougher since these tapes don't bend into a tight radius. I have had mine for about ten years; no splinters or anything like that. I have lost one of the end eyes, so have to just tape the cable onto it.
