Query: Poor batter y design

When it works, it's great. The problem is that almost every time I use it, I have to remove the two batteries, reinsert them and reinsert the battery cover. After I use it once or twice, it stops working until I repeat the above maneuver. I am not sure if it is a problem with the battery compartment design, or perhaps I am "resetting" the device by removing and reinserting the batteries.I tried calling tech support for assistance, but as usual, leaving a message resulted in no reply.I think Hawkings is a high quality company, and I don't understand why they don't want to give better support to this product. Until this is fixed, it is so annoying that I strongly recommend not purchasing it at this time.
