Terrible, ordered sight glasses over 3 weeks ago and they still haven't shown up. Very upset, will never buy anything from you again.

Mugs are great! Free mug is a farce. I was charged $8.80 for the free mug. Then when I pointed out their obvious last of math skills they refunded $1.06. These people are sketchy at best. Do not buy from USA Lab if you care about accuracy. However, if you have money to burn go for it.

seriously?
