This topic is only to share my latest experience with Jim Bartell and his Bartech Focus Device.
I recently bought my 3rd BFD, and the unit arrived in only 2 days.
10 years ago I bought the first one.
7 years ago the second, and now the 3rd.
Always I had a problem with the equipment ( not more than 3 or 4 times in 10 years, and was because focus puller dropped to the floor the unit or burnt for bad connections) Jim helped inmediatly to solve the problem and in less than 3 days the spare parts arrived -and the problems were solved- here in Argentina, below of the world.
I hope all the manufacturers have the service like Jim have.
Thanks a lot Jim!
