MobileSentrix vs Parts4Cells

Reviews from techs
Neither supplier has a published PartsGrade review yet, so we can't say which one has better part quality, defect rates, returns or shipping. We won't guess.
Bought from both MobileSentrix and Parts4Cells?
You're exactly who other techs need to hear from. Review each one on part quality, defects, returns and shipping. About a minute each, no account needed.
Review MobileSentrix Review Parts4CellsTracked part prices
Public list prices as shown on each supplier's site (no login), before account or volume discounts, latest check per listing. Compare the same tier only (see the screen quality tiers guide). “Not yet known” means we haven't recorded that supplier's price, not that they don't sell the part.
No prices recorded yet for either supplier. Most suppliers' terms don't allow automatic collection, so their prices get added by hand. Seen a current price? Send it with the link.
What techs say elsewhere
Public comments from other sites, with a link to each source. These are not PartsGrade reviews, we haven't verified the purchases, and they are not counted in any score.
MobileSentrix
- Positive
my favorite is MobileSentrix, as their prices can be mixed due to demand, but their quality is always top notch
The same commenter also mentions using the MobileSentrix LCD buyback program for cracked screens.

unfortunately, sentrix just isn't that great.
A UK-based repairer who says AliExpress is often much cheaper for them. An opinion without specifics.

They also clearly advertise which parts are oem, but grey market ( Service Pack) and those items which are used, refurbished, or aftermarket.
Cited as an example of a supplier that carries some authorized OEM parts and labels part grades clearly.

I tried MobileSentrix for my first time with an NFC module replacement and it was causing a short circuit
A UK-based repairer's first and only order. They describe it as one purchase, so it's a single data point.

mobilesentrix has great understandable warranty
A shop tech explaining why they honor screen warranties for customers when there's no sign of damage.
