Hey I found out why Lentek does not answer their phone.
They are under FTC investigation for misleading the public on their products. I was surprised since Fred said his super bark free worked so I kept reading.
The FTC is after them for their mosqueto (sp) magnet. The problem is real simple according to the FTC "It just does not work" They did a field test and found no added benifits from haveing one on. (how funny)
So appearantly they have sold out to the Koolatron company and they have assumed the fight with the FTC, now they are in trouble.
BTW Lentek did not make the super bark free, It is made in Germany. However they were the warehouse for that product. If you have one it came from them, one way or another.
Sharper image now has the smaller ones in stock and you can get them locally. According to the store in Southlake :When they are gone theyr'e gone. Sharper image will not order any more until the issue with the FTC is resolved. It has been going on since 2002, and is not settled yet.
The name of the "one" I am trying to get is "Dog Silencer Pro" I have found a web site where these are sold. They are $69.95 retail. I am trying to get to the manufacturer and sell them wholesale. I may go ahead and buy one and get the manufacturer name off the unit and go that route. It is advertised to cover 300'
I tried to cut and paste the web address here but I can't do it.
Don't give up on me, I'll get it.
