Question: Is the selector switch metal or plastic ? Are the tools guaranteed for life?
Document: The tools themselves are nice with good selection. Everything in here is guaranteed for life and while i've never returned a Stanley product, I hear replacements are a breeze. On to the case. Cheap plastic and bits do not fit well. Little Tykes makes higher quality toolboxes than this. Some sockets are too loose and fall out when opening/closing. The spark plug attachment to remove had finger breaking potential it was so stubborn(had to pry it out with a wrench and still took an effort).
Case buttons up real good. Stanley fan for life.
This is a great product to have for a great price. It has most every tool you would need in normal everyday life. Everything is solidly built. Perfect for everyone.
Fantastic tool set. Already used it plenty.One thing I don't understand is that it comes with several drill bits which i've used with one of the sockets. But there should be a tool in the kit, like a screwdriver with retainer. However, I will overlook that because this set a fantastic bargain.The case is well made (plastic) but may break down over time if handled roughly.
This is a great tool set. Quality made tools at a fraction of cost compared to others and a great warranty.
My husband used this the first day to work on the car. He has many of these tools, but they are all in one place and easy to transport.
I have the coolest wife in the world. She was so excited to have a new set of tools. She smiled all day. She loves what the set comes with.
Good tools and everything was nice. Gift wrapping was a waist though, they just put it in a bag..not worth the extra money
Bought this for my husband to use around the house. Is a great starter set. Great quality tools and the case was a bonus!
Tools are good quality and at a good price. Great replacement for tools I had stolen. The added wrenches are A plus
Answer: yes
