This tool was extremely easy to use. Arrived with a pack of additional plugs along with 3 already pre-loaded inside of the tool itself. After plugging the tire, I filled it back with air and rode around for a few minutes. When I got back, my tire pressure was 1-2 psi lower. Using some soap and water, I found that there was still a slight leak. I didn't want to have to insert a second plug, so I decided to just let it sit and checked pressure again it the morning. Today I stepped into garage and found that it had dropped from 38 psi to around 29. I figured, okay... it's a pretty slow leak and I've ridden home before with a leak that was far worse. Filled my air to a little under 38 psi and rode into work (roughly 45 minute ride). Checked the air pressure and it was hovering at 40 psi. This was good news to me since it showed that the leak was either so small that it didn't make much of an impact or perhaps the small leaks corrected themselves overnight once the sticky compound on the plugs have settled itself in.
I just checked my air pressure again (been about 2 hours) and it was at around 37 psi (tire is cold now). So overall, I'd say that this tool was successful at sealing the puncture, and although it didn't seal it 100%, it would be more than enough to get you back home in the event of an emergency. Will update again when I get home today after work.
PROS
---------
Small and lightweight tool
Well built
Easy to use (fixed my flat in less than 5 minutes)
Can use up to 4 plugs in a single puncture
CONS
---------
Might not seal the hole 100%, although you can use up to 4 plugs in the same puncture
Sealing material is a tad small in diameter, which is probably why it might not seal the leak completely
UPDATE 07/22/2015
I plugged the tire this past Sunday and it looks like the leak has gotten worse. My air pressure is much lower by the end of the day compared to Monday. As it turns out though, the problem is not with the tool, but instead due to the fact that I had stopped short of finishing the job. The screw that punctured my tire was a tad smaller than the diameter of a single plug. This is why there was a very slight leak. I decided today to redo the fix which required me to push the 1st plug through completely. The reason being is because I had already trimmed the tail end of the 1st plug, which means I no longer had anything to hold onto as I put in the 2nd plug. This is okay however because Dynaplug customer service notified me that the brass tip is self lubricating and non-abrasive. After applying the new plug, again I noticed that there was a slight leak. I then held the tail end of the plug as I pushed in a 2nd one. As soon as I pulled the tool out, the sound of leaking air immediately stopped. I applied soap and water and found ZERO leaks. Road the bike to a nearby gas station and put my tire back to 40 psi (it was sitting at 30 psi). Rode back to the office and again, applied soap and water to make sure that there are no leaks before I trimmed the tails off. So far, so good! I should have done this from the get go as it would have saved me a bit of headache with having to constantly refill air the last 2 days. Due to this new found knowledge of how to properly apply the plugs, I'm changing my rating to a solid 5 stars. Thanks Dynaplug!

Looks like it was a success! Still no leaks and tire pressure was exactly what it was the day before. Would highly recommend this tool!
