With the right trainer, this type of training is very effective. It doesn't induce a lot of stress in the dog. It creates a set of rules that are easy for the dog to understand.
I would recommend you go watch some training taking place and observe what the dogs look like during training.
Are the dogs stressed out or having fun? Fun is good!
Are they constantly vocalizing or overtly reacting to the stim? If it is obvious when the dogs are being stimmed, the level is too high.
How do the dogs react to the trainer? Are they happy to engage with them? Are the trainers enjoying working with the dogs and creating an atmosphere that is positive? Things should be upbeat and fun.
What do the kennel facilities look like? Clean, happy dogs with the opportunity to exercise a couple times a day other than training?
What type of training does the owner receive? You need to understand how to effectively communicate with the dog, and how to maintain your training. If you are going to be doing maintenance training with the e-collar, you need to have enough training that you understand how to do that.
It bothers me when people label e-collar training as some type of shortcut for general obedience. It is fast because the communication is effective. A good trainer with good timing and understanding of these methods can achieve very good obedience in very few training sessions. If the dog is not stressed out, has no negative effects of the training, complies with commands from the owner and has a great time doing it, how is it a bad thing?
I just don't understand the automatic knee jerk reaction some people have to the e-collar. I see far more compulsive training every day just watching people walking their dogs on flat collars.
When a dog saves the life of a man, it becomes clear that partnership knows no bounds.
