When I needed tracks for John Deere 35D I decided on United Skid, never even tried anywhere else. I ordered on Monday and they arrived Thursday, secured to a pallet. Appear to be high quality, I am sure they will last many years. The only complaint I might have is this - I asked very politely to let me know when they were shipped, or when they might be here. This would be good information to pass along to the forklift driver, etc. Nobody bothered to say a word, and they just showed up. This was not a problem, but what if it HAD been a problem? The company could do better. I have told other people where I bought my tracks and recommend United Skid.
