The only functional addition was to add a new bolt to the two holes for the screws. Great price for all the tools included in this set. The only negatives i can say, is the speaker I received had a few manufactuer flaws. Parfais dans une petite cuisine. After a full charge lasted 45 minutes with one call and listening to music. Four of my Apple lightning cables have deteriorated to the point of non-use and all at this one weak point. Works great on a rug runner, better than the rug holders I?d tried before They look and feel nice. You wont regret, Its best of both without the let down pointers of the touch. Fits very well and fashionable.
