No issues. As expected. Storage solution is a nice addition. Tested against freshly cal'd unit and spot on.

All lids not tightened. Storage solution lid really loose; seal broken causing liquid to escape and run down the bottle, crystallizing around mouth and down sides. Noticeably lower liquid volume in bottle.

I assume these are accurate - my meter seems to calibrate just fine, but for some reason these have a terrible odor to them. My previous sets of calibration solution from other manufacturers never had any odor. I don't know why/what this smell is but to me, it's terribly obnoxious. I would not recommend it for that reason.
