Any comments on those saddle tees that you can simply snap & glue onto an existing PVC sprinkler line to add a new branch for a head?

I put a wood deck in the backyard and now the sprinkler head locations no longer make sense. I have already plugged the ones I don't need but need to add half a dozen heads. I could use slipfix couplings but that's a lot more excavation compared to a saddle tee and my back is kind of sore last week.

I've not used one but have seen them on sewer lines where a cleanout was needed to be installed after the line was already buried. From what I understand, PVC primer and cement "melts" the pvc material on the two mating surfaces, then it rebonds at the molecular level as it cures for a joint stronger than the pipe itself (Oatey says). This is different and stronger than simply glueing two surfaces together with a layer of glue in between. So if done right it looks like the saddle joint would be as strong as any other pvc joint.
