Putting at anything is better than not practicing and as good as putting at the newest, fanciest, most expensive and shiniest basket you can find.
The skill of putting is about consistently hitting a target. Some putts are uphill or downhill or in winds. So long as your target is exposed to the wind it doesn't matter much what it is or how high off the ground it is (within reason, of course
). A post, a tree or a taped X on a trash can are all great targets.
There are many different baskets out there. Most of them do a poor job of consistently catching solid putts to the center of the chains. Bounce outs and blow throughs are not your fault and cannot be avoided by a special technique or putting style or certain kind of putter. So don't worry about what you cannot control and do your best to hit your target. I mention this because there is no benefit to putting at a basket as opposed to another target of the same approximate size (although a smaller target may be even better which is why some players aim at a particular link of chain).
It is far better to putt more at a made up target than less on an official basket. Dip the basket in gold and sprinkle diamonds on it and it still is no better than a fence post with a red dot painted on it.
