    Absolutely high quality !

    Posted by vincent on May 9th 2022

    Absolutely high quality ! It is compactly built so I was able to put in a 10' x 10' room and had zero issues hitting the walls. Awesome piece of equipment for the price. I've been using it for two weeks and no issues whatsoever.

    Great little home gym, it gets the job done. The instructions were pretty difficult to follow at first, so i procrastinated putting it together but once i got the hang of it- it didnt take long definitely need two people to assemble, no complaints using it, other than the cables are really stiff but expected it.

    Decent overall machine

    Posted by Bernie on Jan 7th 2022

    Set up was not the easiest. the plastic guideline parts I broke about 7-8 of these. Extremely flimsy and even after setting them in a pot of hot water to try and soften them up they still broke on install. The pec fly portion of the machine is pretty much useless, the resistance on it is just not quite right plus the set back is a tad too far back to get the correct leverage on it. The smith machine feels a bit weak when using it but it gets the job done. the cable pulls also get the job done but again the resistance feels a bit off especially compared to commercial equipment, perhaps needs some more use to get it feeling more smooth when pulling (I have lubricated every part heavily already) but again; it works. Overall, its a good product and meets my needs but as someone that has been a gym goer for a little over 15 years it leaves a bit to be desired. For the price Id say you are getting your moneys worth though. Its nice that it comes with a lot of the handles in the package. The adjustable bench works good. The seated pulls work good, no complaints there. I wouldnt disuade anyone from getting this but i would consider spending a little extra cash for something you might feel is more solid though. 3 stars.

    Set up = Nightmare

    Posted by Bernard Shaw on Dec 16th 2021

    Multiple parts easily break during set up (Specifically #78). Multiple missing parts on arrival. Attempted to contact customer service at their phone line 1-800-999-8899 - Get busy signal every time. Attempted to utilize replacement parts form online and kept getting error message/captcha not working. Finally someone within the chat bot was able to submit a form for me to order the parts. Will update my review if i ever get the machine functional..

    Great Machine - Not So Great Replacement

    Posted by Unknown on Jul 26th 2021

    I ordered this machine back in May and received it in early June. I read many reviews and took the advice of some others to put the bench together first to get the hang of the instructions. Upon opening the box and laying out/examining all the parts, I noticed two parts that were in pretty bad shape and were already starting to rust. Having read many similar stories, however, I was confident that the company would quickly get me a replacement part and I'd be on my way. Unfortunately, my experience has been anything but that... I called and was told that one of the two parts I needed was on back order and would be received in about 2 weeks. After 2 weeks went by I called for an update and was once again told 2 weeks. After another 2 weeks of waiting and no update, I called again and this time was told that it would be 6 - 9 weeks. So I guess this box will sit for another month or two before I can assemble my bench... I understand that there are challenges and shortages going on, but I'm really disappointed in such a single-threaded supply chain that doesn't allow the company any other options that sitting and waiting for a part to show up from overseas. I'm sure this is a great just seems that I'll have to continue waiting to find out for sure.

    Like many others have stated, difficult to assemble and instructions are vague in some areas. However, it seems the more I use it the better it performs. Be sure to grease all pulleys and areas that slide for better results.

    Good home gym

    Posted by Richard on May 9th 2021

    We purchased this unit because the one we really wanted (MD-9010G) which we have at our TN home was not in stock. I didnt notice when I placed the order that it did not come with the curl bar on the bench. Over all it is a good machine but just not as good as the other unit. It does take a while to put together but not to bad. Seems to be very sturdy.
