I don't write reviews often, but this thing has done me a lot of good in the month that I've had it. I've been using it about 4 or 5 times a week, with fairly heavy usage when I do. I started at two on the dial and have since moved up to 5 and I've noticed a lot of muscle gain in my arms and pecs.No sign of any hydraulic leakage in mine, so that might have been fixed, or was a flaw in a bad batch or something. Hopefully it stays that way. If you order it, I would make sure to go around and tighten all the bolts when you get it, as some of them are loose on arrival. At least for mine.Don't listen to the people complaining about a lack of instruction manual. It's a lever with resistance. Squeeze it in different ways and it will work out your muscles.

In going to be straight with you. This is my third arm strength exerciser thingy just like this one. The first one had springs and though it's ok, I don't like it very much. It's noisy and the bars are too close together.The second one was like this but had the electronic counter and I loved it. But it fell apart after a month.So my approach to this will be first impression, and then a how it's going and finally an I've broken this one too update.I've had this a few weeks now and I'm really liking it. I miss the electronic counter as I personally found that very motivating. But the hand grips are very comfortable and the bars spaced far enough apart that it feels like you are getting a good bit of excersise with it.The hydraulic is nice. It feels so smooth and easy as you squeeze the handles together. Now I've read about these leaking fluids. I manage about a hundred a day with this so we will see how long it lasts.One last thing for now. The settings are very easy to adjust, and I'm happy with that. All it is with this one, a simple dial you turn. I'm on 2.5 or so because I'm a big sissy weakling but it will be interesting to see how long I will be there before moving up a bit.Will update this later.Just a brief update here. It's still going quite strong with none of this hydraulic leakage, so far. I read that in some other reviews but happy to say no issues with it.One thing I did learn is that you want to go round every now and then and tighten the bolts. Phillips screwdriver and a pair of pliers does the job. Once the bolts fall out, one so far, they are a bit of a hassle to get back in again.I've moved up to 3 on the rotating scale thingy and it's much harder to do. So down to about 60 per day as opposed to 100.I've found it's building arm, shoulder, chest and ab muscles effectively.That's all for now. Will update again later.So I got this in June and we are now in September. Time to provide an update.It's going great for me. The bolts do need tightening fairly regularly. I've not experienced this dread leakage of the hydraulic fluid. In fact it's working great so far.I'm up to a three on the rolling scale thingy. My chest has expanded with use and abs have been developing too. This does help activate core muscles and that was unexpected for me.Really glad to have this and I hope it lasts a good while yet.

Love it

Home gym in a box. I like it a lot of adjustment for better results.

It looks very nice and well-made. I have used it for 2 days only, and it performs as expected.

Works Perfect. Easy to use.

Good workout, Strong product worth every penny.

I have it as high settings which is 12. It is a workout. No way. I'm maxing out 400 lb!
