Well most of them like the mower decks are made by the same company no matter what name is on the box.
Here is the biggest problem with the new generation wackers.

This was the worst Idea ever, I bought a rebuilt Royobi split shaft at LHFS as they had them on sale for $49.99 plus a 25% coupon. Had to call warranty, about the string and the fact the gas was leaking out of the tubing and shooting everywhere.
They sent the parts right out and they are getting a lot of complaints about the heads they had a kit already bagged up old style, head ,spool and two different bump knob screws.
The guy I talked to said those heads were creating a problem on all the brands that use them.

New one is the front one the original one is the back, the attachments fit both and a couple of the other brands that had the attachments.

I have picked up most of the attachments other then the snow blower. Useless other then for steps, I have hooked two of the limb saw arms so I can get higher in to the tree while still on the ground. # makes it to heavy and hard to work. The rough wood or pruning saw blades like from Milwaukee. will work in the saw head.
I'm going to drill holes in the slotted head and put brass eyelets in and keep it for a spare.
You can pick up the attachments at sales yard or flea market cheap. The blower works pretty good, the vac is a pain as the bag gets full fast, it does work well with a hose going to a cloth bag that fits over the garbage cans to blow it in to. The edger is great you can use the generic edger blades it they fit the shaft. The roto tiller is also great, it is better than a small foot print 12"wide Honda 4 cycle. that my fathers neighbor talked him in to buying.
The saw blade works on light small dia stuff, but I find I can move faster and cut more with a ratcheting lopper
I love mine and I have the old power head still works, and a new one.
