Query: Cheap Plastic Cracks After A Few Years' Use

I used these stands for about 3-4 years without any problems. Then after years of use, the plastic on the base slowly started cracking, thus pretty much making these stands useless. I can't find any place to buy a replacement bracket at the bottom, so I'll need to purchase brand new stands, but not from Proline.If you're only looking to use them for 3 years, buy them; otherwise, they will not last longer than that!
