Price and rating as shown on Amazon when we collected them. Both change.

The DKN Studio 7400 is a compact single-station home multi gym at £499, second in this guide. DKN describes it as an all-in-one machine with a double pulley system, high and low pulleys, a dual-action chest station covering chest press and pec-deck, an adjustable preacher pad, a butterfly station and a leg developer, built around an 80kg weight stack. The listing gives dimensions of 165cm long, 105cm wide and 210cm high, and a maximum user weight of 120kg.

The figure that doesn't close on this one is the machine's own weight. The final bullet states "Product Weight: 144kg (317.5lbs)", while the spec table lists Item Weight as 64 kg — two very different numbers in the same advert. The stack figure behaves better: 80kg appears in the title, in the fourth bullet and in the spec table as 176.4lbs. The 4.3 rating from 126 reviews is what Amazon displays for the listing.

What buyers actually say

Quoted from customer reviews on Amazon

“took about 10 hours over two days. forget the two multi spanners that comes with the kit, I cannot imagine they would work, use your own spanners and sockets. I am still not sure I got it all 100% but it works lovely and I have a few spare washers left over so I feel I have beaten the system. I am open to criticism here, but without that guidance video on you tube, I would have struggled more than I already did. My tips are;1. only pop the nuts and bolts on the press out cards for each step according to the booklet - so on diagram one in the booklet just pop out step 1 on the card.2. pulley wheels - there is a big bag and a little bag containing 3, don't mix them up. The big ones go as follows (well, it is what I did) one at the very top, where you would use the pull down bar once attached, the next one is directly back from it on the top frame. When you thread the pulley wire through this should become apparent. The last one is at the bottom where you use the leg exercises - in the frame at the bottom.3. there are a couple of time the pulley arms only use one of these said arms. Be careful, I put one the wrong way round and is essentially useless. I can't be bothered to rectify it, but would be very easy to do, just remove the nuts and swap it the other side of the pulley. Just observe what and where the wire is going if in doubt. The wire clicks into the pulley arm and acts as a safety guide.4. watch the you tube video. May have mentioned that before.”

“Arrived within a few days delivered by a couple of helpful guys who put it where it needed to be, Be warned it is heavy.People have said it's a tad difficult to put together but if you follow the instructions step by step carefully and read what it says then you should have no problems, just take your time. If you have space lay the pieces out after taking off the plastic wrappings so you can see what you got.The items are very well packed and you will see that you have a huge amount of packaging to dispose of.Once assembled the DKN7400 is a very solid, well built, well thought out Multi Gym. The quality far exceeds many of the more expensive Multi Gyms on the market. One of the main features is its compactness it fits into a garage gym very well with only a small foot print.It's a pleasure to use, quiet, and assuring, no wobbles or creaks, over all an excellent Multi Gym that's worth every penny.”
