BOOMERANG TOOL COMPANYHunting Compass Retractable Gear Tether, Hook & Loop Strap, 24" Retractable Cord, 4 oz. Retraction, Green Polycarbonate Case, Universal Attachment

I use this to secure a lightweight tool that I use close to 100 times a day to my belt loop. I've been using it for several months with no issues. That's probably close to 8,000 extension/retraction cycles already.Update 7/21/2014: I'm still using this daily at the same duty rate and it's still performing quite well. If it dies tomorrow I would consider it well used, given the frequency with which I use it. I'm probably pushing 20,000 extension / retraction cycles at this point. I would happily purchase a replacement if I needed to, but I don't get the sense it's planning to give out any time too soon.Update 2/5/2016: This thing is still going strong and I use it ~100 times/day, 5 days/week. It's probably close to 100,000 extension / retraction cycles by now. A year ago I snagged it on a ladder and kinked the cable loop at is the attachment point for whatever you connect to the retractor. I found that a cable type keyring worked well as a replacement, so I swapped it in and kept using it. Today, I noticed that a few strands of the cable have broken, so I need to replace the cable again. However, the body, the clip, the spring and the line are all functioning as new. I'll snap a new cable in the end and keep on using it. I bought a couple more T-REIGN Retractors when I came across them on sale to have as backup. They're still in the packaging and it doesn't look like they're going to be pressed into service any time soon. Color me impressed!Update 2/7/2017: Chalk up another year of daily use ~100 extension / retraction cycles every workday. I wore out a second cable loop so I just replaced it with another cable style keychain loop, which fits just about like the original steel cable end loop. The thing is still going strong. The spring shows no sign of weakening and the dacron line shows no signs of wear. Truly outstanding durability.Update 2/7/2018: Another year of hard use in the books. I managed to finally wear out the tether a couple of months ago, so I replaced it with 100lb test dacron fishing line that I already had (it's just about identical to the original line). I disassembled the retractor to replace the line. When I had it open, I was impressed by the robustness of the spring and the quality of construction. I've been using this thing every working day for 4 years now. It's accumulated an incredible number of extension/retraction cycles by now. I'm very impressed by this tether.Update 1/2/2022: I have since retired but the retractor I reviewed is still going strong. It doesn't get used nearly as much anymore, so I assume that it will outlast me.NOTE: the product that I wrote this review about was manufactured by T-Reign. They are now being advertised as Boomerang Tools. I assume that this means the original company or product was bought-out. Oftentimes, when this happens, manufacturing gets moved and/or materials get changed to reduce manufacturing costs. I have no idea if the current "Boomerang Tool" device is in any way equivalent to the "T-Reighn" device that I purchased and reviewed. I hope that it is. Caveat Emptor...

I use these when fishing. I clip my knife to one and a flashlight to one. I use the medium so I have 3’ of cord when using my knife or light but they save you tools if they ever come out of your pockets

Update 12-6-2018: I've had this item for over 4 years now and it's still going strong! Other than the initial problem, nothing else has gone wrong with this. The cord is still in great shape, all the plastic components are unbroken, the tension is still great, it reels in just fine. I use this every work day. If something ever happens to this one, I'll be getting another. In fact, I might just order another one anyway, just in case it breaks in 10 years.-------------------Prior to purchasing this I had my work keys on a cheap carabiner, and would detach them from my belt loop each time I'd need them, which was very often during the work day.I chose the model with the belt clip as opposed to the style with the small carabiner, since it's much easier to remove this style than the other if needed.I like the quick-release end. But, it's difficult to release, requiring a lot of pressure in just the right spot. It doesn't seem like the plastic will take a lot of releasing and re-attaching with the kind of pressure required to release. So I removed one star.Overall the item is easy to use, isn't noisy when pulling the cord out, as others have mentioned (maybe the manufacturer made a change). And since the cord is kevlar, maybe it will stop a bullet for me some day ;)Recommended.Update 03-31-15: A major flaw with this design keeps rearing its ugly head. The small braided metal loop where the keys are held starts to come apart after about three months. It happened the first time in late December 2014, and T-Reign sent me a replacement at no charge. Now it's happening again. It's nice that they sent me a replacement the first time, but I don't think they're going to do that forever. I emailed them again to see if they'll respond, but I'm going to look for another style of retractable keychain. This one isn't cutting it.Update 04-10-15: The T-Reign folks have come through for me. They sent me a replacement, and an alternative replacement for the part that keeps wearing. So instead of the braided metal loop that starts coming apart after a couple months, they sent an alternative with a split ring (which I didn't know was an option). I actually removed the split ring and added a small S carabiner so I can add and remove keys easily. so I'm very happy with the replacement. I've upped my review to 4 stars, I can't in good conscience give 5 stars due to the flaw in the initial design. But I give 5 stars for customer service.

Seems durable but every time I shift or move slightly, with this clipped to my belt loop, it makes a distracting clicking or rattling sound. Think of it as a small plastic drum that resonates every sound of a keyring moving against it. I wear my keys wrapped in a nylon “silencing” sleeve, attached to this retractor. At meetings at the office, folks are always looking around for what is making all that clicking noise? Embarrassing and disruptive.Probably great for fishing or for hands on work environments. Not great for church or office.

Eigentlich nicht schlecht, Rolldose, Kevlarschnur und Karabiner sind von guter Qualität. Einzig die Drahtschlaufe an der letztendlich der Schlüssel befestigt wird ist totaler Schrott. Nach 10 Monaten war diese kaputt. Es befanden sich nur ein Zutrittschip und 2 kleine Schlüssel für Vorhängeschlösser daran, also praktisch kein Gewicht, welches diesen defekt rechtfertigen würde. Schade! Rücksendung über Amazon war problemlos, der Verkäufer "Asaz Enterprises Inc" reagierte auf meine Anfrage gar nicht!

update:Leider hat sich auch bei mir die Metalöse nach einiger zeit aufgelöst und damit das ganze teil nutzlos gemacht. für den preis kann ich daher jetzt nur noch 1 von 5 sternen vergeben.original rezension:Ich habe den Key-BAK jetzt seit Dezember 2017 im täglichen Einsatz. Bisher sind keine Defekte oder Verschleißerscheinungen aufgetreten.Meistens trage ich daran Wohnungs-, Firmen und Autoschlüssel und noch ein Schweizer Messer.Manchmal mache ich daran auch meine Kamera fest wenn ich irgendwo am klettern bin und nicht riskieren will dass Sie mir aus der Hand fällt.Was man hier noch verbessern könnte wäre die Halterung wo das Drahtseil einrastet, das löst sich manchmal und ich habe schon ein paar mal den Schlüssel verloren. Zum Glück meistens im Auto, allerdings sollte genau DAS eigentlich nicht passieren!Weiterhin finde ich Größe & Gewicht wirklich wie schon erwähnt wurde am oberen Akzeptanzbereich. Wenn sich da noch was machen liesse wäre fein.Das Material macht bisher auch alles gut mit. Mal sehen wie sich hier die Haltbarkeit in den nächsten 6 Monaten und länger bewähren wird.Ich würde 3,5 v 5 Sternen geben.

Anfür AIX ein gutes Teil, nur könnte die spannfeder etwas stärker sein, für ein ein kleiner Schlüsselbund ist es ausreichend, nicht für schwere Gegenstände nur bedingt.

Nach über drei Jahren im Dauergebrauch und Reparatur (neue Schnur reingezogen), ist jetzt die Feder in der Halterung ausgeleiert. Nochmal zurechtgebogen, wird noch eine Weile funktionieren und dann durch den Neuen ausgetauscht. Definitiv der beste Schlüsseldings bisher, daher direkt nochmal gekauft!

Die Schlüsselrolle ist zwar etwas größer als angenommen, aber in der Verarbeitung und Funktion super.
