Excellent customer satisfaction, strong sturdy high quality bar that's cheap and easy to assemble
Limited in the range of door sizes it will fit and max user weight is not as high as some other doorway pull up bars
If you have a doorway somewhere between 28" and 34" wide and no more than 5.5" deep and you are not approaching the 250lb limit this is a great cheap buy
The Stamina Doorway Trainer Plus is a very strong steel made door way pull up bar, which can also be used for push ups, doorway situps and supposedly dips - though as with the other doorway bars that all claim you can use them for dips; you'll get hardly any range of motion.
What the Stamina bar does do great is satisfy it's primary purpose, that of providing a cheap pull up / chin up bar which you can easily mount in your doorway with no fixings required.
The padded foam grips of the Stamina doorway trainer is very similar to the CXP chin up bar and Iron Gym Total. You don't get the wide grip support or the more varied range of doorway size support on the Stamina that you do with the Iron Gym, the Stamina will fit 28" to 34" vs Iron Gyms 24" to 34", but the Stamina bar is a little cheaper.
Maximum user weight is 250lbs, which again is not as high as the Iron gym, but unless you're over 250lbs that's not going to mater to you.
All in all as long as your doorways are somewhere between 28" and 34" wide and no more than 5.5" deep and you are not approaching the 250lb limit this is going to be a great buy.
