Product review (5 stars): Did not come with the odd size hard to get battey
I feel really stupid.  I left a bad review because it did not seem to have come with a battery.  But it did.  I did not look in the bottom of the pacageing.  So to the supplyer I am so sorry.  I should be mote careful as one never knows id they are an evil mega corperation or a mom and pop shop like us.  And reviews can make a or break a business.  Sorry about that.  It works great.  Ussing it in my grow tray to grow Romain lettus seeds.

Did not come with a battery.  Frustraighting.  Its one of the little round ones like in a garage door opener.  So u csnt use it out of the box.  I am so frustraighted with amazon. I order about five things a week.  All the asian electronics stuff doesnt come with bateries and worse adapters or power chords and even directions.
