Biggest issue was losing dart because fishing line broke. I resorted to tying line to ring. This workaround worked fine.One time it worked and well and very accurate. Then the fishing reel hung up. It is impossible to fix and doing so wastes precious job time. Great idea bad fishing reel choice. Maybe they will send a new one. Update: they did, will see how second one worksThis was purchased used, so there was a learning curve because it didn't come with an instruction manual. I watched a couple of youtube videos, and those really helped. Attach the line to the small hole at the bottom of the dart, not in the large loop as one video posted.The fish line was all tangled up in the reel, and after fighting with that, it seemed easier to spool new line. I bought 10 lb test for a few dollars. There are several good videos for spooling a reel, check the ones for Zebco because that is what it on the CableCaster. Once that was done, it worked as advertised. There is a safety on this, so if you can't pull the trigger, try releasing the safety. Also, be sure to press the large black button on the back cover of the reel before firing.A small flash light fits in the holder and does help in an attic. Cable was run in a residential attic using the CableCaster, and the CableCaster was helpful. It is important to look at possible obstacles before shooting the dart because there are many things that can impede the dart when you go to retrieve it such as the duct work. The dart shoots level which is a huge help because an arc would limit its usefulness in close spaces.The body of the gun does seem cheap, like a dime store water pistol, but the firing mechanism and fishing reel are solid.Works really well it definitely shortens the time spent running new drops.Decided to get this to make cabling a small office network easier. It did the trick! Certainly pricey, when you consider the quality of the device. Looks like a cheap, plastic, child's dart gun from the 1980's that you'd have bought at a drugstore toy rack. Even when you put the darts in, it sounds like the same spring sound that my childhood toys made. This item certainly has a more powerful spring to toss the dart quite a distance though and it worked as advertise. Given the plastic construction of the device, I'm just not sure how well it's going to hold up, but as I'm not a professional, its not something I'll use much. The fishing reel attached to the front is a low-end product, but then again, it does the trick. For the price, I would have expected a little better construction and material. I'd certainly be cautious about buying this if I was in the business of installing networks as I doubt it would hold up with daily use very long. It needs TLC that I doubt a professional would fail to give it on a big job.I wanted to love this, but I don't. I bought it specifically to get cables across and inaccessible 40 foot section of trusses. Glow sticks did not work for this scenario. The monofilament came off the dart many times, it was inaccurate and did not work in this application. Maybe it works in other applications, but it did not work for me.It will get tangled easy if you're not being careful, but it has extra string inside in the case you cannot detangle it. lacks instructions on detangling and rebuilding the string. otherwise it can save time in certain situations.Cheaper then a laser line cast gun and pretty much the same (less powerful throws,no laser etc) some complain of strain pulling the cable but I pull back string or light rope and pull the rope itself to pull my cableLa fleche va quand meme assez loin, dans les plafonds, un peu difficile si il y a peu d'espace, mais est très pratique !!! La corde à peche pourrait etre plus solide, mais sinon, superbe produit !!!Es una excelente herramienta para esos trabajos de difícil ejecución en cuanto a trabajar con plafones ciegos.Te facilita el ejecutar algún cableado extra, hasta instalaciones provisionales ocultas.Lo recomiendo el 110%.They suggest using glasses for a reason.This thing is pretty strongWorks great! Can run lines where I couldn’t before.I love this thing makes my job way more easy
