The Power-Pak 445 (PP445) by Universal (a division of Nautilus) is an adjustable dumbbell set that allows you to adjust the weight of the dumbbells from 4 to 45 pounds in 5lb increments. Traditional dumbbells are expensive. They typically sell for around $1 per pound, and take up a lot of room. If you're at a gym this isn't a problem. If you're working out from home, it is a real pain to store 7 or 8 sets of dumbbells, and bring them out and put them away after a workout. I am a big fan of adjustable dumbbell sets. Not only do you usually save money, but you get a lot more variety which makes your workouts faster and more efficient, and prevent clutter in your house. The only disadvantage to them, is that they're bigger than standard dumbbells, which can limit your range of motion in some exercises, and you can't drop them or be as rough with them as regular weights.

Below are the major brands of adjustable dumbbells that Amazon sells in the 50 pound range. I've listed them based on a combination of popularity and rating based on what I think are the best to least best, with the Bowflex SelectTechs (which I'll refer to as BST) at the top. I currently use the BST and I think it is the best adjustable dumbbell option right now, so the rest of my review will compare the PP445 to them.

1. Bowflex SelectTech 552 Adjustable Dumbbells (Pair) 5 to 52.5 lbs in 2.5 pound increments
2. PowerBlock Classic Adjustable Dumbbell Set 5 to 45 lbs in 5 pound increments

I was not sure if I should get the Bowflex SelectTech 552 Dumbbells or the Universal Power Pak. The Bowflex SelectTech 552 don't seem to be very durable. There are YouTube videos showing the plastic selector plates break easy and they show how to repair with glue since they are breaking so frequently. They also talk about ordering other parts on EBay for repairs, so apparently there are issues with other parts. They also say you need to set the dumbbells down gently in order not to break the plastic selector plates. I needed dumbbells that are durable. Sometimes I can't set dumbbells down gently due to I am exhausted after the set. You also have to set/adjust the weight on BOTH sides of each dumbbell. I thought the Bowflex may be nice since you can adjust in 2.5 lb. increments up to 25 lbs. But then I started thinking that I have never been able to adjust conventional type dumbbells in 2.5 lb. increments, so what's the point.
Based on the aforementioned, I purchased the Universal Power Pak. The Universals have been great. You can set/adjust the weight on either side of each dumbbell, which is very convenient. They come with a stand, but you don't need to use the stand if you want to save space. You only need the trays the dumbbell rests in. The trays can sit on the floor, table, or mounted to the stand. I saw other reviews where some said they don't like the stand design because it doesn't use a pedestal. The stand design is great because it DOESN'T use a pedestal. The stand design allows you to more easily store stuff under it. Some other reviewer complained about the weight plates being noisy clanking together. I do not see this as a problem at all. They are quieter than the old school steel weight plates on a dumbbell hand bars I had been using. I hope this review helps others. It was very difficult for me to decide between the two types. I have been very happy with this purchase.

I considered the Bowflex 552's and these, the Bowflex 552's looked nicer, but were more expensive. I was going to buy the bowflex at $280 (at the time lowest I could find). I figured a $30 difference and I would make-do without a stand. Glad I did not, because after using these I realized the stand is a must have, and then would have been talking $170 difference. Here are the Pro's and Cons that I found between the 2.

Bowflex-Pros 1.-Look cool 2.-2.5 weight increments at low rates Cons-1.-Cost 2. Occasionally "stick" 3. Need to turn both ends to adjust weights

Universal 445-Pros 1. Come with stand 2. Only turn one end which makes changing weight easier and quicker 3. Less physcial plates so one less plate to "tetris" in 4. Price Cons-1. Adjust in 5 increments (I have not found an issue though) 2. Weights do shift-they are secure they just slide back and forth (I have gotten used to)

I am happy with the Universal 445's and am glad I purchased rather than Bowflex, based on price and quicker weight adjusting. They also look cooler then in the pictures. The 5lb increments is fine for me, since I had been jumping like 10lbs with standard dumbbells.

The only con I can think of is the shifting weight, which I could imagine drives some people nuts. Yes the weights shift, but that are still secure and they aren't going to fall off, I have confidence to do lifts with them over my head, face or crotch.

I have been using these for over a month now in the P90X workout. They are quick & effortless to change the weight selection. I really like that you can change the weight from either end of the dumbell. They are solid while in motion with just a little juggle, much like the plate dumbbells that I used for years and so I find it very normal. I love the stand. It is a nice & necessary bonus, making it quicker and easier to adjust the weight, pick them up and set them back in place after you have just curled what felt like 1000 lbs (and your arms are burning and exhausted)

I placed my stand on a sheet of 3/4" plywood, cut to the size of the base of the stand, that is mounted on heavy casters so that I can roll the entire weight setup to where I need it very effortlessly.

At first I was worried about not having increments smaller than 5 lb weight changes, but find that by the time I feel a need for more weight, I would always increase by 5 or more lbs anyway. Having smaller increments (like 2.5 lbs the bowflex do) would be a wasted feature for me.

All in all, I am very happy with the purchase of these and recommend them to all I talk to.

***UPDATE***

Just completed P90X and starting on my second go-round of great workout program!!! These weights have worked flawlessly and I am totally glad that I got these. I am able to keep my workouts moving along at an uninterrupted pace, which keeps the heart rate up, the muscles burning and the blood pumping!! I amm sooo impressed with these that I am buying a second set so that my son can workout along with me. I feel that these are the best-bang-for-the-buck adjustable weight sets there are. Only thing I find that I wish for at this point of my training is more weight!!! I wish they made a set with more weight........ I would totally buy it this time around!!
