The grinder is well made (China) and works well. I'm a retired machinist and well versed on machine use, so with that said. The manual does not give instructions on how to use it and Bradley referred me to You Tube for a customers video, WOW! This man had no clue, no safety or knowledge on how to set it up or use it correctly.
Bradley does not have their own video. If you check out the competition's compony video you will get what you need to set up and operate this grinder correctly and safely.
After that I got it set up and working, I sharpened 3 set of 48" JD tractor blades, did a good job, 2 sets of 60" JD blades that where beat to crap, took a bit of time but I did save them.
Have a balancer, measure in from the blade end to where edge stops try to keep them the same length (this will aid in the balancing)
Keep a bucket of water to cool the blade as you grind, never let it change color from heat, this will soften the edge and will not stay sharp.
Never sharpen to a sharp edge, keep about 1/32 blunt edge.
Never grind the end or back of the blade (only if it's nicked or burred)
Most blades are about 30 degrees.
**The debris (dirt) catcher also includes an adaptor for wavy type mulching blades (comes with S100 kit) also shown in competitors video (how to use it).
All in All it is worth it.
It's also a bit less cash out of pocket then competitors.

Review update
I my review of S110 kit, I also added the angle grind support. This speeds the set up by 75%
It is a very useful add on, I recommend it.
Replace the standard support, drop the wheel to 1/8" from it when it's set to the angle and grind.
Most blades are 30 degrees but it's a quick adjustment to change it.
Very nice

A Beautiful Lawn or the Bare Minimum: What Kind of Grass Do You Want?

It’s something so simple, but it really matters: Your lawn’s appearance depends a lot on whether you keep your lawn mower blades sharp! Sharp lawn mower blades produce healthier, more attractive turf. Dull blades may chop down all the vegetation, but can also damage your lawn.

Why Is it Important to Sharpen Your Lawn Mower Blade?

Your lawn mower doesn’t actually cut your grass. That may not be what you expected to hear, but it’s true. The blades tear the grass. If you notice frayed brown tips of your grass every time you mow it, you can be sure your blades are dull. A sharp cutting edge gives a good quality cut and does less damage to the turf.

If you have turf in your front yard, it makes sense to maintain it properly. A ragged garden lowers the curb appeal of your home, which can affect its value. Sharpening your lawn mower blades is a small thing to do to help maintain the value of your home.

How Often Should You Sharpen Your Lawn Mower Blade?

Whether you enjoy mowing your lawn or find it a tedious chore, most people don’t enjoy sharpening mower blades. So, it’s useful to know how often you should sharpen the blades to get the best effect.

According to a poll of professional lawn care services and landscaping experts, sharpening every 25 hours of mowing is optimum. For them, it is about once a week, but for you, knowing your timing is necessary. Obviously, the time it takes to mow your lawn depends on how many square feet it is. What you need to do is check the time it takes to mow it and calculate how many mowing sessions it takes before you have reached 25 hours. This is good news because of the unpopular myth that you should sharpen the blades after every mowing!

Most people don’t own a mower blade sharpener because they don’t realize how important it is. We can help. We offer an easy-to-use bench grinder and other models that will help make lawn mower blade sharpening a breeze. When you use the right tool, you get the correct sharpening angle and won’t damage the blades.
