Ascentiz H PRO

It works really well, and Ai mode is especially intuitive, but I wish boost mode had a button on the belt.

I'm 54, 6'1", and 200 lbs. I've used this for walking, jogging, hills, and stairs, and it really does give you extra assistance. The regular assistance is fairly subtle, so I prefer having it turned all the way up to level 5. What surprised me most was taking it off afterward. My legs suddenly felt slow and sluggish, which made me realize how much it had been helping.

The AI mode works well at recognizing what you're doing and switching ambulatory modes (walking, jogging, running, walking up stairs, etc.) automatically. It isn't instantaneous, but it usually figures things out within about a second or one or two steps. Going upstairs or downstairs, it takes a couple of steps before the appropriate mode kicks in. It even recognized the incline of my driveway and switched to uphill mode.

Boost mode is where you really feel the power. The assistance is very strong and honestly pretty fun. It lasts about 30 seconds, followed by roughly a 30-second cooldown. My biggest complaint is that I have to use the phone app to activate it. If there's a way to do that from the controller on the waist belt, I haven't found it.

You can use the device without your phone in Ai mode, but manually choosing individual activity modes requires the phone app. That gets annoying because the waist harness makes my pants pockets harder to access, so you need to store your phone in a different pocket or maybe mount the phone to the harness or your arm. Fortunately, the AI mode works well enough that I usually don't feel a need to select modes myself.

The app showed an estimated range of about 14 miles based on my use. I haven't walked that far with it, so I can't confirm the full range, but battery life seems good so far.

My 82-year-old mom also tried it. She has severe arthritis in her ankles and difficulty walking and climbing stairs. Unfortunately, she didn't feel much benefit from the regular assistance, even on stairs. Boost mode was too strong for her and made her feel uncomfortable, so she immediately wanted it turned off. Based on our two experiences, I see this as something for someone who already walks and balances comfortably and wants extra help with activity. It wasn't a useful walking aid for her.

It feels lightweight for what it is, and there's a surprising amount of power packed into it. I haven't taken it hiking yet, but after trying it on hills, I'd be interested in bringing it along for a strenuous climb. I'm happy with the assistance and how well the AI responds. Having boost available directly on the belt controller would make it much more convenient. I also wish it included a 100w charger. I had to buy that separately, which seems an odd thing required to do given its price.

Makes walking up steep trails way easier and takes the pressure off my knees. It just feels a bit awkward to sit down on a bench with it on. Otherwise, very happy with it.

Walking a 75-pound Labrador up steep neighborhood hills twice a day was wearing me out. This device completely takes the strain off my hips and lower back. Clips on fast, motor is barely audible, and the battery easily lasts several days of walks for me. Highly recommend.

Live in a hilly neighborhood and used to cut my walks short all the time. Been using this all week and the difference on the way up is crazy. Doesn't feel clunky or restrictive either. 10/10 purchase.

Received the H pro models, obsidian. Got them (one for me and one for the wife) up and going, working well. Haven't used the app (probably won't). Awaiting the knee module. Pretty excited for that, with how well the H module works.
