I purchased a few items & these worked out but didn't use the 135° elbow. Generally speaking, the push fit connectors were ideal for my small repair in an awkward space. Just remember, these are use only once fittings.
Goo quality product, easy to fit even for an amateur.
They make a tidy job coming out of plastic into copper . Not cheap though , but heck I'm worth it
Unimpressed - it leaked despite it being an expensive and respected brand
