Suggestion on hearing aid brands?

Hi all,

My son recently had diagnosed with hearing loss in one of his ears. The audiologist we consulted has prescribed for hearing aids. I have never used hearing aids in my life so as my family. This is the first time we are going to get the support of hearing aids to my son. So we are not sure which hearing aids/brands are best. I have found an affordable hearing aid in Toronto at the Hearing Solutions. The brand that I have found is Phonak. Does anyone here have experience using this brand before? If so please share your reviews. Thanks.
