"I used it to repair some threads on a motorcycle head and they worked like a charm."
"Once I extracted the broken bolt I was able to drill out the hole, counter sink for the insert, thread the hole and place the insert in about 10 minutes."
"I'll just recommend you double-check the angle needed for the new threads before using the drill bit."
"When this is used in conjunction with the Time-Sert inserts, you will become the master of your project."
"Sure you could just tap a new thread, but if you were in my situation, a stripped stud in the soft aluminum of the final drive of your motorcycle, it does not really solve the problem."
"This is the only way to go with thread repair."
"Doing any automotive work or restoration on a German vehicle, you will need this eventually."

"The Time-sert drill bit was just slightly larger than the helicoil hole which made it fairly easy to clean out the pulled threads once I removed the old coils."
"Another perk: The outer diameter of the insert is smaller than helicoils, so if it does fail (seems really unlikely) you can drill it out and start again without losing much material... Helicoils require going quite a bit larger, losing lots of base material every time. If you're really anal, you could add a drop of red Loctite (not included) to the outer insert threads for peace of mind."
"I knocked off one star because it would have been nice to have a drill guide to make drilling the hole perfectly straight easier. I was able to make my own with a wood block and drill press but I could have saved the trouble if the kit had included one."
"How fortunate I checked some forums before buying and replacing my oil pan."
"Worked great and easy to use on my Polaris 4 wheeler to replace the oil plug."
"Everything you need is there minus the hand tap and some skills in tapping."

"Changing out spark plugs on my 2001 Honda civic got to number 3 cylinder on it started to get super thight and you could feel the threads starting to strip I thightened it back in so I could still drive it until I had the money to fix ( time sert kits are expensive over $200 for the kit) then I found this kit ordered it and worked great only took about an hour with a few beers while doing the job."
"Seems to be holding though, and allows you to use the original spark plug style, unlike one of the other repair kits that forces you to change to the "long reach" style plug, which could cause a check engine light."
"This product is amazing it literally took me 20 minutes to fix my F 150."
"Make sure you out a ton of grease on the tap to catch all the aluminum shavings, then I used a thin metal rod with q tips taped to it so I could reach down in the spark plug "valley" to pull up any loose shavings."
"I used it on my '84 toyota pickup (22r), and I really disliked cutting into that aluminum head but it seemed to go ok. I managed to hit the piston while I was threading (hand smacks forehead) so make sure you either don't get all cavalier with your wrenchin' or ensure your piston is out of the way."
"I used this to fix my stripped threads on my 2005 Ford Crown Victoria."
"cb360 blew a plug and I bought this to replace it."

I am also not as confident in this repair as I was in the Time-Sert repair but since this costs about 10% what the Time Sert does this was the right choice for my 14 year old truck."
"This worked fantastic for my 2000 Suzuki Hayabusa to repair my stripped oil pain drain plug threads."
"The threading tool that came with is very high quality and made some beautiful threads."
"Word to the wise, put a dab of grease on the tap and def wrap a piece of tape around where the extension plugs in so when you go to pull the extension out you don't lose the tap in the tube and have to try and get it out."
