Thinking of Buying a Weight Machine and Body Fat Checker – Should I Buy or Not? What Should the Price Range Be?

Hey everyone! I'm considering buying a weight machine and a body fat checker for personal use, but I’m not sure if it’s really worth it. Do you think these tools are helpful for tracking fitness progress, or are they just unnecessary gadgets? If I do go ahead with it, what should I look for in terms of quality and accuracy? Also, what price range should I consider for a reliable one without overspending? Any recommendations would be appreciated!

Thanks in advance!
