These little planers are very effective, but perhaps more important than the brand is how you use them. I've had my makita for more than 20 years, I think. I've planed a lot of wood.
1. wax the table.
2. feed the wood with the grain
3. If you nick the blades, shift them slightly and put them back on.
4. Don't get in a hurry (good advice for power tool use in general). Take a couple small cuts rathern than one larger cut.
5. Don't expect to return to a measurement and match thickness on two boards. Run the boards you need to be the same thickness at the same time.
6. For the last cut, take off as little as you can and still get something out of the chip exaust. You might also feed shorter boards through at a slight angle.
7. The biggest source of error in these small planers is to make boards thicker on one side than the other. Plane an 11" wide board and check the thickness on each side. A small difference can mess you up in furniture construction.
8. Button your sleeves or wear a short sleeved shirt.
9. Wear hearing protection, even if you doing just one board.
10. Keep out of reach of children. Planers are especially bad because you can't see the blades, and they have a slot; kids like to stick their fingers into slots.
