So I've tried a few over the years and honestly, the Vello BG-C10 Battery Grip for Canon 70D, 80D, and 90D is the best bang for your buck technical-wise. It has decent gold-plated contacts that prevent those weird power communication errors you get with realy cheap knockoffs. It's a total lifesaver for ergonomics without the massive "Canon tax" price tag... gl!

so basically, I totally feel u on the ergonomics—shooting vertically without a grip is a nightmare for the wrists!! technically speaking, the main diff with the Canon BG-E14 Battery Grip is the magnesium alloy frame and legit weather sealing, which matters if you're out in the elements. but if youre looking for a solid mid-range option, i highkey recommend the Vello BG-C10 Battery Grip for Canon 70D, 80D & 90D. its better than the super cheap ones cuz the contact pins are way more reliable... i've seen some budget grips cause "Err 01" codes on the 90D because the connection is loose. the vello feels reallyyy sturdy and the shutter button has a nice tactile click. plus, it handles the high-speed burst of the 90D without lagging. definitely worth the slight premium over the absolute cheapest ones imo. gl with the shoots! 👍

yo, i feel u on the wrist strain—long events are basically impossible without a grip. honestly, adding one is a total game changer for the ergonomics alone. i've shot with the Canon BG-E14 Battery Grip for ages on both my 80D and 90D, and in my experience, the build quality is actually worth it if you’re doing serious work. over the years, i've tried many different setups. here is how they stack up imo:
- **Option A (The Pro Way):** The Canon BG-E14 Battery Grip. It’s built like a tank. The buttons have that precise tactile feel, and more importantly, the weather sealing matches the 90D body. If youre shooting in dusty or damp conditions, this is the one. It literally feels like part of the camera frame.
- **Option B (The Smart Value):** I highkey recommend the Vello BG-C10 Battery Grip for Canon 70D, 80D & 90D. It’s way better than the super cheap ones. The rubber grip feels legit and it doesnt feel like it's gonna flex when you put a heavy lens like the Canon EF 70-200mm f/2.8L IS III USM on it. It's the best balance of price and performance.
- **Option C (The Budget Route):** The Neewer Vertical Battery Grip for Canon EOS 70D 80D 90D is fine if youre just starting out, but the dials feel kinda mushy and the plastic is a bit thin. i had a budget one once that actually drained my batteries while the camera was off... super annoying. so yeah, if you can swing the extra cash, get the official one. but the Vello is a solid runner-up if you wanna save for glass instead. honestly tho, once you go vertical, you wont go back lol. gl with the choice! peace 👍

late to the party but i gotta chime in since im super paranoid about my gear... honestly i agree with matthew on the official one. if youre shooting weddings or paid events, that peace of mind is worth the extra cash imo. i've seen too many cheap grips fail at the worst time. here is how i look at them:

• Canon BG-E14 Battery Grip is a total tank. the buttons have that same tactile feel as the camera body and the weather sealing matches the 90D perfectly. no chance of it shorting out your camera.
• Meike MK-70D Battery Grip for Canon 70D 80D 90D is probably the best safe budget pick if you really cant do the canon. it fits snug, tho the dial is a bit clickier than id like.
• Vivitar Battery Grip for Canon EOS 70D 80D 90D is basic but gets the job done for hobbyist stuff. just be careful because the plastic isnt as reinforced and it feels a bit hollow. tbh i usually tell people to just save up for the official one or find a used one in good shape. i've heard horror stories about third party pins getting stuck or damaging the battery compartment, and i wouldnt risk a nice 90D body over a few bucks.
