Great prices!

Easy ordering process! Well designed site!

easy

Very good products, very fast shipping, will definitely buy from them again

I was satisfied with my purchase. It was difficult getting a high gloss, but I think that was because I didn't sand the surface smooth enough. Oh well! I may sand lightly and reapply.

All good.

zz

My only issue ....you don't give me a date on when to expect their arrival?? Also your description says for "1"....hopefully one is one pair?
