I started detailing 11 years ago with a porter cable 7424xp. It was for it's time a great little machine. By today's standards it's underpowered. After two years I moved up to a rotary. I burned a couple panels learning it but eventually became quite comfortable and quick with it.My only issue with the rotary is the potential for hollograms. If I'm jeweling paint, hollograms are virtually non existent. If I have to correct mildly damaged paint I usually need to step up to more aggressive products and pads. With good technique you can avoid most but you usually still need to step down to finer polishes and gentler pads to clean up any that do occur.What I really wanted was something that could remove light swirling and marks and finish off without holograms in one step. With a rotary I found I usually needed at least two steps.This finally solved it and is a huge improvement over the porter cable. The rotary obviously works faster if you're doing a multi step detail, but if you're doing a one step correction this is significantly safer not only in terms of burning paint but virtually impossible to instill holograms. It doesn't replace my rotary though. I find jeweling with an ultrafine diminishing abrasive like menzerna sf4500 requires the power of a rotary and the finish is still better on the rotary than this.My first test was with a 2014 Honda CRV that has close to 200k miles, drives back and forward through LA and Vegas and has never been waxed or sealed. Needless to say, my work was cutout for me. I used this alongside a Lake Country orange pad and 3D Speed all in one. Cut through the grim, left a nice shine, and cleared up probably 90%+ of the imperfections. Night and day difference. It's not perfect, but that wasn't what I was going for anyways. Just a quick cleanup to make the car look newer.In terms of stalling issues, I had to install the included spacer behind the backing plate as it was contacting the plastic shroud. Once installed stalling wasn't an issue. Obviously, this will still stall on creases and angled portions on the car. It's designed to do that so you don't burn through the paint. If you've used a porter cable you'll know it can be difficult at times keeping the pad moving on these angles. If you're coming from the PC you'll understand how you need to angle and position the pad to keep it spinning. This I say is slightly better on the creases but on the flats is where this really shines. The pad really moves in comparison to the PC and does wonders for paint correction.I'd say they nailed it in terms of the clutch stalling. On the flats it spins extremely well even under pressure. On the edges it's sensitive enough that you can still keep it spinning but does slow down to prevent burning.Noise level is on part with the porter cable. I'd still recommend hearing protection.Overall 5 stars from me. Great price, power, and handles well!
