I'm not sure about the 5-star reviews or if my purchase arrived missing accessories. I thought I'd be able to have a barbell, two dumbbells, and two kettlebells. But with the accessories I received, i can either have one barbell or two dumbbells, because the way it's assembled, you have to choose between one barbell or two dumbbells. Also, you can have only one kettlebell at time, so I don't understand why it comes with an extra handle. I thought about exchanging assemblies during my workout, but it's not practical. So I decided to workout with one barbell and one kettlebell and keep that way. Also, the bars are all plastic, I'm not sure how much weight it will carry without breaking it. In the dumbbell mode, the bar is too long, so it scratches my skin when I'm working out. As a barbell mode, it hits my knees when I'm doing the sumo squat because the bar is long enough. The square shape is a bit odd, I should have ordered the black one. I wish I had more accessories so I didn't need to keep exchanging pieces as it is unpractical when I'm exercising. I've been using it though. Overall it's a good value, but I don't know how durable it is due the plastic parts
