Yes, some techs. like them, some don't.
When i first started doing appliance repair back in 1987, i used to love using them, it seemed to solve all the compressor start and run issues, but as they have changed the compressor design in the early 90's , i saw that the 3 in 1 ones that i was putting on would start failing on some compressors, so from then on, i quit using them all together, except for a emergency, till the original relay/overload part I ordered arrived.
So its basically your call.
