Let me preface by saying I’m a 45 year old female with arthritis setting into my finger joints. I got this thing together, by myself, in about an hour at 10pm on Saturday because I was awake and bored. Yes, the instructions are terrible – but common sense should get you through it. The fit is tight and getting your hand inside to hold the nut is a bit challenging – but hopefully you only need to put them in once. Yes, the center panel is flimsy and doesn’t fit flush – but you aren’t making a milkshake. Unless you plan to roll this down a hill at top speeds, I think it will hold alright. So far it only has one banana peel inside – and it’s doing just fine sittin inside there.
