Ader Heavy Duty Adjustable 14"-16"-18"-20" Plyometric Platform Box- Club Level

I love how sturdy and stable this is! I read that it's a pain to move between heights and I haven't tried yet. However, I think that for whatever workout I choose, I would choose the height I need and use for the whole workout without trying to have to change the height during a certain workout. I would definitely recommend. I don't feel worried that I may jump on it and it collapse on me.

Pros:1. This is the best priced metal adjustable plyo box that I found with a very large platform of 20x28 inches (requirement of mine). Free shipping helps too.2. Building materials are good with steel thickness ranging between 11 and 12/13?gauge (thicker tubing at base and angle iron under platform, thinner walled tubing for vertical legs)3. Fully welded construction with bolts used to secure plywood top.4. Somewhat inefficient packaging with at least an entire roll of packaging tape used, gobs and gobs of bubble wrap and multiple layers of cardboard (outside layer was a box from a table tennis product?) but it was protected enough to survive the frustrated UPS guy (50lbs and fully assembled=big and heavy).5. Very stable with no wobble on a flat floor. I’ve zero safety concerns using this for jumping.Cons:1. Not the best, not the worst welding quality. Found a 4 inch piece of MIG wire sticking out of one weld, not the prettiest beads and mediocre cleanup/sanding prior to paint. Precision and attention to detail are lacking.2. Poor fabrication causing severe friction between the outer/inner legs while trying to adjust. Due to the fully welded construction, and no wiggle room, the legs need to be perfectly positioned during fabrication for all 4 legs to line up and slide smoothly. The opening of an upper leg looks to be beat with a hammer or bent with pliers to get it to accept the lower leg so they obviously do not line up well. Calling this adjustable is a stretch as I would not want to beat it into a new height mid workout, but technically it does go up and down with some elbow grease. One positive of this is when you pull all the pins the platform doesn’t suddenly drop so no pinched fingers.3. Paint is chipped off around several welds upon arrival and mild rusting is present in several spots due to paint missing.4. It has a grid of angle iron supporting the underside of the plywood which is welded together but mostly only on the flats (only the bottom of the L, not the vertical section). This could have been much stronger with a little more work with a cut off wheel and extra welds to resist the tension load.5. Would have liked to see a 3/4 inch plywood top as listed on the Ader website rather than what looks to be 1/2 inch plus a ribbed plastic covering. Also, if this is powder coated it’s very thin/cheap.Summary:Overall it’s a good design with some room for improvement in the quality control department and fit and finish. I am using this for a PowerBlock dumbbell stand so size, height and strength were most important to me. If adjusting height frequently is important to you I would look elsewhere to avoid the frustration/time required. If you need a larger than usual platform size, this is a good option for a reasonable price. After some spray paint it will serve its function for me.

Very sturdy; nice rubber top and steel frame. Does not move when you land on it. It is a solid piece of equipment. It arrives assembled but VERY securely wrapped in bubble wrap and clear tape (in fact it is somewhat hard to cut through the tape and wrap without damaging the paint on the metal. Changing the height takes some time and effort, and is mildly frustrating, but this provides some extra confidence that it will stay at the selected height when you land on it. Recommend.

Excellent

The feet slide off and can be a bit awkward trying to set height but overall this is a great product that is sturdy and eliminates storing multiple plyo boxes. It is very sturdy and one can jump up and down as hard as one wants without moving or breaking the platform.The feet will actually grip the floor which is why the feet slide off at times.

I like the stability of this unit, adjusting its height is laborious.
