For the money this is amazing!
Style: Corded
I love this rotary tool. Mind you it’s not a 150$+ dremmel but it is a workhorse and very reliable. I see these comments of disappointed people saying it’s not up to there standards and there dremmel is better. I don’t understand that. This is a 20$ rotary tool and the best one for that price you can find. Most of these reviews are comparing to high end expensive dremmels and that doesn’t make sense to me. Anyway I like the rotary tool very much and the first thing I did was buy the keyless Chuck made by wen so I don’t have to deal with collets and have them wear out or keep changing them when I need to use a different size bit. Best investment I made. Makes life so much easier. I ended up buying 2, one for the rotary and one for the flex shaft. Also if you have never used a flex shaft you need to understand that you have to take the collar off and slide the insert out of the flex shaft so you can clamp the rotary tool on it and then screw it on where you removed the collar. I recommend every 20 to 30 hours of use with the flex shaft take the insert out and wipe the grease off and reapply a light amount of grease. That way it doesn’t heat up. I’ve found that with this particular flex shaft graphite does not work so well like other models. It will get hot with graphite. I’ve found that Valvoline red high temp bearing grease works the absolute best. You can buy it in the tube here on Amazon or at you’re local auto parts store. The high temp is what you need and it prevents grease from melting down into the handle of the flex shaft. All in all this is a win win if you understand how to maintain and take care of it. I originally got one of these because my grandfather has one and it’s over 12 years old and it’s still working. Probably has a couple thousand hours of use on his. Take care of you’re stuff it will take care of you…

Impressive Sound Deadening Solution with Enhanced Audio Quality
Model: NewSLS50_52
I recently purchased the Siless 50 mil (1.3mm) 52 sqft Car Sound Deadening mat, and I am delighted with the results it has delivered. Right from the start, I was impressed with the packaging, which ensured the product arrived in perfect condition.
One of the standout features of this sound deadening mat is its ease of use. It was a breeze to cut and modify according to my specific needs. Whether I needed to cover specific areas or customize the size, the mat accommodated my requirements effortlessly. This flexibility made the installation process a breeze.
The Siless Sound Deadening mat has proven to be highly effective in reducing outside noise within my vehicle. With just a half cabin install, I noticed a significant reduction of approximately 10 decibels, making my driving experience much quieter and more comfortable. The mat acted as a reliable barrier against external noise, allowing me to enjoy a more peaceful ride.
Furthermore, the sound quality from my vehicle's audio system experienced a noticeable improvement. The Siless mat effectively dampened vibrations and minimized resonance, resulting in cleaner and more refined audio output. The mat's thickness of 50 mil (1.3mm) ensures optimal sound absorption, contributing to its effectiveness in creating a quieter and more enjoyable driving environment. I can now appreciate the full range of tones and enjoy a more immersive music experience during my drives.
Overall, I highly recommend the Siless 50 mil Car Sound Deadening mat for anyone seeking a reliable and effective solution to reduce noise and enhance audio quality in their vehicle. The easy cutting and modifying process, along with the excellent packaging, contribute to a seamless installation experience. With a significant reduction in outside noise and an improvement in sound system performance, this sound deadening mat has exceeded my expectations.
