Adding a two year update because, man, this set is still going strong. There's minor wear from weekly use but no where near needing to replace anything. Most impressively, the bands aren't yet worn where they fold through the door anchors--the first thing that went on my old bands. I think it's a combination of smooth rubber of the bands and the wide, smooth fabric of the door anchors. I love using it so much that I received a few more accessories for it this holiday--the heaviest, neon band and the protective sleeve so I don't need to keep finding my shoes to protect my feet. I also got a bionic bar--different company--to try. Very impressed with the quality and value of this set, and I recommend it to anyone wanting to swap the gym for an at-home workout. I've done resistance band workouts for a while, enough to wear out my old bands. This replaces them and more. I bought this set because it includes two heavy resistance bands, which makes it a bargin compared to buying a regular set and then buy those bands individually. With the extra two bands, I can do pull-downs with as much resistance as I need, and it saves having to double up bands for arm workouts. I originally thought having two sets of handles and door anchors was too much (and I still have the handles and anchor from my old set), but I do find it useful to have an extra pair to save time switching bands all workout long. The carabiner hooks can shift around in storage, and it takes extra fiddling to get them into position to change bands, compared to my old set where the clips were sewed into place. I find I have to prep everything ahead of time for a fast-paced workout, so having the extra handles and anchors helps. I do feel like I'm constantly fidgeting with things now, though it's getting better as I get more used to getting clips moved around and knowing which bands I'm going to need next. [2 year update: the fabric's all broken in and slides right into place. I'd forgotten I used to have so much trouble with it.] The handles have some room to slide. I like this, as it makes it easier to do hammer curls and tricep extensions. I actually wished they slid easier (my old pair of handles have a much thinner nylon strip so they slide easily), but I know some people don't like them to slide at all, so I think this makes for a good compromise between the two extremes. The door anchors work well. It feels like there is a rubber donut sewed into the end. Compress it, and it slides through the crack in the door and then pops back open to lock in place when the door is shut. I have not used the ankle straps yet. [2 year update: again, the nylon fabric's softened over time so it's easier to slide the handles into the position that I want. There's no sign of wear on the handles. There's some wear from the door squeezing the anchors but no where near worn out. I've used the ankle straps and they are comfortable.] It has taken me some time to adjust to all the band sizes and possible configurations. I will never understand why companies "color code" things but make the colors completely random, so I have to keep a sheet with all the colors and resistances written down next to them. The weight estimates seem fairly accurate--when I grab a band based on its resistance range, it seems pretty comparable to doing the same move with a free weight. The bag holds all the gear with room to add a jump rope. I love that can now carry equipment for an entire cardio and strength workout in one bag. That said, it's a big bag. It resembles a large college text book in size. My scale says it weighs around 3.5 lbs altogether. Alas, if you are looking for something to put in your carry-on while you travel, this isn't it, unless you pack really light or just bring the bands you'll need. It does fit in the bottom of my jogging stroller, so I can get a workout in at the park while the kids play. I have only used this for a couple of weeks, so I cannot vouch for how it holds up long-term, but I do not notice anything that would make me think it won't last. April 2019 Update: Five years and counting and still going strong. The nylon webbing on my purple and orange band had some minor fraying so I called the company and they sent out two free replacements absolutely no hassel. I am so impressed.)
