Product review (4 stars): Good For Storage of Eye Medication
I bought this to keep eye medication in.  The medication is to be stored at 36 to 77 degrees.  The label on the eye drops suggest keeping it in a refrigerator.  This applies both to my wife's medication and mine even though they are different.  This Mini USB Fridge allows us to keep our medication upstairs.  That makes it more convenient for us to take just before bed time.

Only the metal plate on the bottom of this Mini Fridge gets cold.  It is not insulated.  The air inside is near or at room temperature.  I do not think this little machine would work good for keeping a can of soda cold.  But I can not say that for sure because I have never used it for that purpose.

Our vials of medication come in two sizes; 2.5 and 5 ml.  I have even put some over the counter eye drops for dry eye in there.  They come in 10 and 30 ml sizes.  All of these containers are made out of plastic.  The two smaller containers get cold all over. They are about one inch high.

The top of the 30 ml container does not get cold.  It is about 2 inches tall.  This larger container does not have the temperature storage requirement of the medication.  It is required to be shaken before using.  So these over the counter eye drops do feel like cool relief when applying.

For our purpose of eye medication storage and convenience this Mini Fridge is almost perfect.
