andis power groom good or bad

[Siberian Mom]

i am a dog groomer and was woundering if anybody have used the andis power groom clippers. i have th e andis ag single speed clippers now and its time for a new pair but i dont want to go out and spend $150 on clippers that i really dont know about. i know there smaller and have 4500spm but how are they to groom with and durability and are they compatible with the A5 blades. i have had a pair of oster A5 but they were to niosey and scared the more timid dogs and they burn your hand. i have found the andis ag to be pretty quiet and theres no need for greesing, which i like. if anybody has feedback id love to hear it
