The soft start circuit in my half inch Porter Cable router quit and after opening it up to repair it, I saw how skimpily the soft start circuit in it is built and I didn't really want to repair it only for it to puke again later.
I checked around for another option and luckily I found the GS11 universal soft starter.
So I bypassed the built in soft start circuit in my router and ordered a GS11.
It worked great out of the box not only on the router but everything else in the shop that I could think to plug into it.
Confession:
As an electrical engineer I could not help but to open it up and take a look at it's construction and I was happy to find it very well laid out on a high quality PC board with quality components. Also, I saw that many of the power handling components are very robust and many are even overrated for their function.
The thing may well outlive me.

Now my DWE7491 ramps up when it starts instead of sounding like it’s going to come apart. Not sure why DW doesn’t add this feature.

I share my workshop breaker with a few other rooms and got tired of resetting and turning off other high current devices every time I started my table saw or air compressor. This soft starter did the trick.

GT23 Universal Soft Starter (15A max. Heavy duty)

I’m liking it so far. It does what it’s advertised to do. I haven’t had it long enough to really get to know it. I don’t like all the emails asking me to review it. They start as soon as you get the product.

Worked as expected. Well made.

Made big difference, in how my 40+ year old Craftsman, 1/2 horsepower radial arm saw starts up. I used to have to give the blade a little nudge to get it started, even on a 20amp breaker from grid power source. Now using grid or solar power, it starts up smoothly. Almost spins up my, 1/2 horsepower swamp cooler from my solar array battery bank, but my inverter still kicks out. Am confident once I get a larger inverter that can handle more in rush current before tripping. (my 3000w inverter cuts out at 2 seconds, just before the soft start finishes ramping up) the swamper should work just fine too. The swamp cooler does spin most of the way up though, before the inverter cuts out, and does so rather smoothly. Though I will have to figure some way to wire the water pump separately, as it doesn't like the soft starter, and doesn't need it to function better.

Very glad I decided to go ahead and purchase the GS10.

I had a 15A circuit with a TV, a small (250w) IR lamp and 4 LED spot lights on my enclosed porch, but the problem was I would trip the breaker, or at least turn of the TV when I turned on the 1500w heater. It was a quartz heater that I connected to the GS10 and it works perfectly, now. The coils slowly ramp up and it doesn't matter what is off or on, I don't have a problem any more.

5 stars. We live off the grid on a solar powered battery system and we wish we had known about this minor miracle years ago. No more household shut downs when the water pump kicks in. Highly recommend.

Always get the continuous duty soft starter! I was actually able to wire this to a switch on an old cinema projector and it starts up beautifully! You should definitely 100% buy this one.

We purchased the GS10 soft starter to solve the abrupt startup on our commercial sewing machine. The GS10 immediately fixed the problem after it was installed. Great product and terrific customer service. Five stars!

Works great

Eliminated my reset trips to the breaker box and provided an added plus of smooth starts for my miter saw.

seems to fit the bill for my application

Used the soft start to help with initial load on startup form an air compressor on a inverter system in a service truck. Works extremely well and keeps the inverter from shutting down.

I have a 2000 watt Honda generator that i wanted to use to run my 12 Amp air compressor...120 volt x 12 amp= 1440 watts with. The generator would not always get the compressor going because of the innitial high kick.Therefore i thought this Soft start would allow it to absorb the surge...but i was wrong.
