I buy several things from them. Bought a hay mower and sent it back because the quality was poor. Most of what I buy is hardware type things. Their wrenches are pretty good but China made, thats what I use in the tractor tool boxes. I can't recommend any of their equipment.
I use them anytime I can. There customer service is pretty good, I ordered some sprayer nozzle bodies and they shipped the wrong ones. All I had to do was call them up and they sent the right ones.
So..50/50 split so far. I ordered a replacement bale spear and nut for 1/2 the price of TS. We'll see how it holds up. First time I've ever called to get on a mailing list.
