Is the sonic system more efficient than the rotary?

It depends on the sensitivity of your skin. My skin breaks out like crazy with the rotary, but the sonic system is really gentle, so it doesn't irritate my skin.

I do not know but if I was you I would steer clear of sonic blade. I have purchased two and both have had faults which could not be rectified

I don't know. I use them for trophy and haven't used any other machine to compare. They are necessary for trophy.

Not much. If any difference at all. However, the 500 RC unit is better, because hit has more functions

The Marpac is the better seller because it's been around longer and is established. I own both and the LectroFan is much better because it is versatile and (most important to me) you can adjust the deepness of the pitch. On top of that, you have ten steps of volume from very low to very loud (the Marpac is somewhere in the middle and only has high to higher pitch).

We bought this one because of the reviews of it being quieter and having a stronger motor. We love ours, but have never tried the other model.

I dont know exactly but it is a noticable difference. Accelaration is greatly improved, top speed does not change much. But u do need a bigger muffler to dampen the sound.

I've actually owned both of them and the more expensive one is much more effective at cleaning your teeth. You get what you pay for in this case? The batteries do run down quickly on the cheaper version. I usually carry the cheaper version on vacation so that I don't have to bring my charger for my more expensive toothbrush. It's more convenient. :)

Actually my cordless DeWalt vibrated more than any of my rotary hammers including Milwaukee (cordless) and Bosh (corded). My cordless Milwaukee Sawall vibrated less but doing actual cuts, I couldn't tell the difference.

Model ST255 just spins but it is sonic. A higher end product model ST257 sonically pulses and infuses.

M1 is portable while S1 is not. In terms of quietness S1 is better then M1. The suction power is also better.

In any tool that involves grinding, cutting, vacuum, etc. it pretty much comes down to motor size. The Elite has a bigger motor. More power equals not only a task better done, but far less chance of overtaxing the killing the motor because it isn't being asked to constantly perform at the outer edge of its capabilities. Reserve capacity usually equates to a longer lifespan.

Not as noisy as gas saw. It seems though, that noise and power are closely related.Not as powerful as gas saw.

The shaver works either way, but plugged in it seems to have a little more power. I switched to Braun after being a norelco rotary user for years but it was not cutting my neck hairs and the cutter heads were too expensive. You get a carrying case, little cleaning brush, a little bottle of oil, the cord, and the operating instructions. A very good razor for the money!!

Yes there is a difference whe it comes to replacing the toothbrush head. I have the Arm & Hammer Spinbrush Proclean sonic recharge. I have purchased 4 different packs of toothbrush replacement heads and none of them fit. Every one I purchased said Arm & Hammer spinbrush Pro clean but the inside of the brush on my toothbrush requires a full circle inside. Plus it just snaps on there are no arrows on the head of brush or handle which requires a 90 degree twist so that the arrows line up & the brush is locked in as well. All the ones I have purchased have a half circle inside of head of toothbrush with arrows to line up so that brush is locked in.

Hi! No, it is not bothersome at all. When working with this tool, one can only slightly feel the vibration (especially on the highest setting). Th noise of the Sonicrafter is way more noticeable than the vibration. Best regards, Marc Wuttke
