Great value and a nice size that won't expire before I use it all. Solutions were accurate and came with certificates. pH 10 buffer read 0.02 higher than indicated on paperwork, but the 10 buffer is the hardest to keep stable and needs to stay fresh, so that's not bad. Other pH 10 buffers I have received have been off by as much as 0.45. These will be my go-to pH buffers if the price remains this reasonable.

They came in and are doing great, we are glad that the expiration dates are far out, We don't use a lot of this, so our standards usually expire before the bottles are empty.
