[ Edit 03/05/23... Forgot to include make/model info. "Triplett TeleTalker 330 Lineman's Test Set / Butt Set with ABN Test Clips (3330)" Also forgot to mention that it is nicely packaged, if that matters to you at all. It's in a sturdy, glossy white box with magnetic-secured opening flap. End edit 03/05/23 ] Pro's... 1. Cost. This was the cheapest "real" buttset available. 2. Build. Not built like a tank, but reasonably solid and should withstand some amount of being knocked around. 3. It works. For one-off tasks it gets the job done. 4. Belt clasp, Cord w/ strain relief and Angled Bed of Nails (ABN) are of decent quality. Cons... 1. Shake it and something rattles inside (probably the ear transducer, but I haven't taken it apart yet to find out). Doesn't inspire confidence in the construction. 2. No speaker capability; you have to hold it up to your ear to find out if there is dial tone. 3. Other buttsets have a "voltage detected" LED that lights green or red (reverse polarity); this one only lights when reverse polarity is detected. When voltage is present with correct polarity, there is no visual indication that voltage is present. 4. Nomenclature states "weather resistant housing" but I don't think I would chance using it in the rain, probably should stick to indoor use only.
