Quality products, excellent customer service
The vials vary in color from batch to batch, sometimes a lot. I order blue and sometimes get a dark, navy blue and other times get a very light sky-blue. That is not a problem for me--but was a surprise when some vials changed hues!
The plastic inserts which allow each CRC to function will sometimes be missing from the vial lids. Usually out of each case of about 400 items, there are sometimes as many as 12 without lids, which means that those vials are useless too! Some batches and sizes are worse than others. I haven't tried getting any replaced or anything so that may be something for you to try.
I'm still planning to use these, however.
quick response to order! exactly what we ordered!
